2.1 Introduction

The PCI audio and videobroadcast decoder SAA7134HL is a highly integrated, low cost and solid foundation for TV capture in the PC, for analog TV and digital video broadcast. The various multimedia data types are transported over the PCI-bus by bus-master-write, to optimum exploit the streaming capabilities of a modern host based system. Legacy requirements are also taken care of.

The SAA7134HL meets the requirements of PC Design Guides 98/99 and 2001 and is PCI 2.2 and Advanced Configuration and Power Interface (ACPI) compliant.

The analogvideo is sampledby 9-bit ADCs,decoded by a multi-line adaptive comb filter and scaled horizontally, vertically and by field rate. Multiple video output formats (YUV and RGB) are available, including packed and planar, gamma-compensated or black-stretched.

2002 Dec 17 4

Analog TV soundis digitized andstereo decoded (NICAM anddual FM standards).Audio isstreameddigitally viathe PCI-bus or routed as an analog signal via the loop back cable to the sound card.

The SAA7134HL provides a versatile peripheral interface to support system extensions, e.g. MPEG encoding for time shift viewing, or DSP applications for audio enhancements.

The channel decoderfor digital video broadcastreception (ATSC or DVB) can re-use the integrated video ADCs.

The Transport Stream (TS) is collected by a tailored interface and pumped through the PCI-bus to the system memory in well-defined buffer structures. Various internal events,or peripheralstatusinformation, canbeenabled as an interrupt on the PCI-bus.

PCI audio and video broadcast decoder SAA7134HL

The SAA7134HL incorporates two 9-bit video ADCs and the entire decoding circuitry of any analog TV signal: NTSC, PAL and SECAM, including non-standard signals, such as playback from a VCR. The adaptive multi-line comb filter provides superb picture quality, component separation, sharpness and high bandwidth. The video stream can be cropped and scaled to the needs of the application. Scaling down as well as zooming up is supported in the horizontal and vertical direction, and an adaptive filter algorithm prevents aliasing artifacts. With theacquisition unitof thescaler two different‘tasks’ canbe defined, e.g.to capturevideo to theCPU for compression, and write video to the screen from the same video source but with different resolution, colour format and frame rate.

TheSAA7134HL containsTV sound stereodecoding from Sound IF (SIF), for NICAM standards and dual carrier FM systems, as used in European and Asian countries. Basebandstereo audiosamplingis alsoimplemented, e.g. for capturing from a camcorder or externally decoded BTSC. Theaudio samplingrate canbe locked tothe video frame rate to ensure synchronization (lip-sync) between the video and audio data flow, e.g. for storage, compression or time shift viewing applications.

The SAA7134HL incorporatesanalog audio pass-through and support for the analog audio loop back cable to the sound card function.

The decoded video streams are fed to the PCI-bus, and arealso appliedto aperipheralstreaming interface,in ITU, VIP or VMI format. A possible application extension is on-board hardware MPEG compression, or other feature processing. The compresseddata is fed back throughthe peripheral interface, in parallel or serial format, to be captured bythe systemmemory throughthe PCI-bus. The Transport Stream (TS) from a DTV/DVB channel decoder can be captured through the peripheral interface in the same way.

Audio, video and transport streams are collected in a configurable FIFO with a total capacity of 1 kbyte. The DMA controller monitors the FIFO filling degree and master-writes the audio and video stream to the associated DMA channel. The virtual memory address space (from OS) is translated into physical (bus) addresses bythe on-chiphardware MemoryManagement Unit (MMU).

7.2 Application examples

The SAA7134HL enables PC TV capture applications both on the PC mother board and on PCI add-on TV capture cards. Figures 5 and 6 illustrate some examples of add-on card applications.

Figure 5 shows the basicapplication tocapture videofrom analog TV sources.The proposed tuner types incorporate theRF tuning function andtheIF downconversion. Usually the IF downconversion stage also includes a single channel and analog sound FM demodulator. The Philips tuner FI1216MK2 is dedicated to the 50 Hz system B/G standard as used in Europe. The FI1236MK2 is the comparable type for the 60 Hz system M standard for the USA.Both typesare suitedfor terrestrialbroadcast andfor cable reception. The tuner provides composite video and baseband audioas mono or ‘multiplexed’(mpx) in case of BTSC. These analog video and sound signals are fed to the appropriate input pins of the SAA7134HL.

Further analogvideo input signals, CVBSand/or Y-C, can be connected via the board back-panel, or the separate front connectors, e.g. from a camcorder. Accompanying stereo audio signals can also be fed to the SAA7134HL.

Video is digitized and decoded to YUV. TV sound is digitized and decoded to stereo audio, according to NICAM or dual FM standards. The digital streams are pumped via DMA into the PCI memory space.

The SAA7134HL incorporates means for legacy analog audio signal routing. The on-chip audio DACs convert the digital decoded stereo signal into analog audio. This analog audio input signal is fed via an analog audio loop back cable into the line-in of a legacy sound card. An external audio signal, that would have otherwise connected directly to the sound card, is now routed through the SAA7134HL. This analog pass-through is enabled as default by a system reset, i.e. without any driver involvement and before system set-up.

During the power-up procedure, the SAA7134HL will investigate the on-board EEPROM to load the board specific system vendor ID and board version ID into the related places of the PCI configuration space. The board vendorcan storeother boardspecificdata inthe EEPROM that is accessible via the I2C-bus.

The application of the SAA7134HL is supported by reference designs and a set of drivers for the Windows operatingsystem (Videofor Windowsand WindowsDriver Model compliant).

The SAA7134HL captures this TS via the dedicated peripheral interface into the configurable internal FIFO for DMA into the PCI memory space.

The packet structure as decoded by the TDA10045 is maintained ina well-defined buffer structurein the system memory, and therefore can easily be sorted (de-multiplexed) by the CPU for proper MPEG decoding.

The Broadcast Driver Architecture (BDA) for Windows operating systemssupports this type ofhybrid TV capture application, sharing one capture board for analog and digital TV reception.

7.3 Software support

7.3.1 DEVICE DRIVER A complex and powerful software packet is provided for

theSAA7134HL. This packetincludesplug-and-play driver and capture driver installations for all commonly used 32-bit Windows platforms.

All platform related drivers support the following:

• Video preview and capture interfaces

• Audio control and audio capture interfaces

• Custom application interface, that enables the

development ofspecialized applications in cases where the published Windows Application Program Interface (API) such as WDM or VfW is not sufficient.

Table 9 Microsoft Operation System (MOS) support

MOS DRIVER SUPPORT

Windows 95 Device access is containedwithin a VxD. The Videofor Windows(VfW) capture driver interfaceis a

16-bit user-mode interface.

Windows NT4 Device access is contained in a kernel-mode driver. The VfW capture driver interface is a 32-bit

user-mode interface.

Windows 98 Device access is contained with a kernel-mode Windows Driver Model (WDM) driver. The capture

driver interface is also kernel-mode WDM. Windows 2000 The driver is binary-compatible with the Windows 98 driver. Windows ME The driver is binary-compatible with the Windows 98 driver. Windows XP The driver is binary-compatible with the Windows 98 driver.

7.3.2 SUPPORTING WDM The WDM driverfor Windows 98 and Windows 2000 (see

Fig.7) is a kernel-mode driver that implements a Kernel Streaming (KS) filter with output pins for audio, video preview, video capture and VBI, together with a crossbar

for input source selection and optional connections for other on-board devices as child drivers. The WDM driver is implemented as a stream class mini-driver. It also exposes the external interfaces to support the user-mode 34API DLL. Custom applications and debug tools will continue to work without the need to load different drivers.

7.3.3 SUPPORTING VfW The traditional Video for Windows (VfW) interface is

supported for Windows 9x and for Windows NT4.0 (see Fig.8). In both cases a 32-bit capture driver based on the SAA713x user-mode API (34API.DLL) controls the video functionality and the user-mode audio driver implementation.

The capture driver supports direct draw surfaces for live video and is able to capture video in packed data formats and in planar formats. TV applications such as Intel intercast and Philips teletext are supported by a private VBI extension.

In the event that VfW has to be implemented as a 16-bit interface under Windows 9x, a thunk layer is included for connecting the16-bit interface tothe 32-bit capturedriver. Old 16-bitapplications usingVfW arestill supported inthis way.

• Capture transportstreams (MPEG data) from achannel

decoder chip (OFDM, VSB, QAM) for supporting digital TV applications, or from an on-board MPEG encoder chip that is fed by the video output port of the SAA7134HL

• Capture raw VBI sample stream to a stream of buffers over the PCI-bus

• Access to the I2C-bus master for controlling other peripheral circuits.

The 34API transfers thedevice driverfunctionality through a proxy interface to the user-mode. The proxy interface adapts to the different kernel-mode implementations, so that the common 34API can be used on all Windows operating systems in the same way.

The SDK for the SAA7134HL contains the detailed description of all software components such as API documentation forstreaming, tuner control, dialogues and direct draw control.

The provided sample code will introduce the user into working with this interface.

7.4 PCI interface

7.4.1 PCI CONFIGURATION REGISTERS The PCI interface of the SAA7134HL complies with the

“PCI specification 2.2”

and Advanced Configuration and Power Interface (ACPI) as required by the

The PCI specification defines a structure of the PCI configuration spacethat isinvestigated during theboot-up of the system. The configuration registers (see Table 10) hold information essential for plug-and-play, to allow system enumeration and basic device set-up without dependingon thedevice driver,and supportassociationof the proper software driver. Some of the configuration information is hard-wired in the device; some information is loaded during the system start-up.

The device ID is hard coded to 71 34H. During power-up, initiated by PCI reset, the SAA7134HL

The powermanagement capabilitiesand powerstates are reported in the extended configuration space. The main purpose of ACPI and PCI power management is to tailor the power consumption of the device to the actual needs.

The SAA7134HL supports all four ACPI device power states (see Table 11).

Thepin PROP_RST ofthe peripheralinterface isswitched active LOW during the PCI reset procedure, and for the duration of the D3-hot state. Peripheral devices on board of the add-on card should use the level of this signal PROP_RST to switch themselves in any power-savemode (e.g.disabledevice) andresetto default settings on the rising edge of signal PROP_RST.

Table 11 Power management table

POWER STATE DESCRIPTION

D0 Normal operation: all functions accessible and programmable. The default setting after reset and

before driver interaction (D0 un-initialized) switches most of the circuitry of the SAA7134HL into the power-down mode, effectively such as D3-hot.

D1 First step of reduced power consumption: no functional operation; program registers are not

accessible, but content is maintained. Most of the circuitry of the SAA7134HL is disabled with exception of the crystal and real-time clock oscillators, so that a quick recovery from D1 to D0 is possible.

D2 Second step of reduced power consumption: no functional operation; program registers are not

accessible, but content is maintained. All functional circuitry of the SAA7134HL is disabled, including the crystal and clock oscillators.

D3-hot Lowest power consumption: no functional operation. The content of the programming registers

gets lost and is set to default values when returning to D0.

7.4.3 DMA AND CONFIGURABLE FIFO The SAA7134HL supports seven DMA channels to

master-write captured active video, audio, raw VBI and DTV/DVB Transport Streams (TS) into the PCI memory. Each DMA channel contains inherently the definition of two buffers, e.g. for odd and even fields in case of interlaced video, or two alternating buffers to capture continuous audio stream.

The DMA channelsshare in time and space onecommon FIFO pool of 256 Dwords (1024 bytes) total. It is freely configurable how much FIFO capacity can be associated with which DMA channel. Furthermore, a preferred minimumburst lengthcan beprogrammed, i.e.the amount of data to be collected before the request for the PCI-bus is issued. This means that latency behaviour per DMA channel can be tailored and optimized for a given application.

In the event that the FIFO of a certain channel overflows due to latency conflict on the bus, graceful overflow recovery is applied. The mount of data that gets lost becauseit couldnotbe transmitted,ismonitored (counted) and the PCI-bus address pointer is incremented accordingly. Thus new data will be written to the correct memory place, after the latency conflict is resolved.

7.4.4 VIRTUAL AND PHYSICAL ADDRESSING Most operating systems allocate memory to requesting

applications for DMA as continuous ranges in virtual

address space. The data flow over the PCI-bus points to physical addresses, usually not continuous and split in pages of 4 kbytes(Intel architecture, most UNIX systems, Power PC).

The association betweenthe virtual (logic) address space and the fragmented physical address space is defined in page tables (system files); see Fig.10.

TheSAA7134HL incorporateshardware support(MMU) to translate virtual to physical addresses on the fly, by investigating the related page table information. This hardware support reduces the demand for real-time software interaction and interrupt requests, and therefore saves system resources.

7.4.5 STATUS AND INTERRUPTS ON PCI-BUS

The SAA7134HL provides a set of status information aboutinternal signalprocessing, videoandaudio standard detection, peripheral inputs and outputs (pins GPIO) and behaviour on the PCI-bus. This status information can be conditionally enabled toraise an interrupt on thePCI-bus, e.g. completion of a certain DMA channel or buffer, or change in a detected TV standard, or the state of peripheral devices.

The causeof anissued interrupt isreported in a dedicated register, even if theoriginal condition has changed before the system was able to investigate the interrupt.

7.5 Analog TV standards

Analog TV signals are described in three categories of standards:

• Basic TV systems: defining frame rate, number of lines per field, levels of synchronization signals, blanking, black and white, signal bandwidth and the RF modulation scheme

• Colour transmission: defining colour coding and modulation method

• Sound and stereo: defining coding for transmission.

TV signals that are broadcasted usually conform fairly accurately to the standards. Transmission over the air or through a cable can distort the signal with noise, echoes, crosstalk or other disturbances.

Video signals from local consumer equipment, e.g. VCR, camcorder, camera, game console, or even DVD player, often do not follow the standard specification very accurately.

Playback from video tapecannot be expected to maintain correct timing, especially not during feature mode (fast forward, etc.).

Tables 12 to 14 list some characteristics of the various TV standards.

The SAA7134HL decodes all colour TV standards and non-standard signals as generated by video tape recorders e.g. automatic video standard detection can be applied, with preference options for certain standards, or the decoder can be forced to a dedicated standard.

The SAA7134HL incorporates TV stereo decoding for NICAM and dual FM sound systems. BTSC and EIAJ are demodulated to mono-aural sound, but stereo decoding can be added externally. Baseband stereo audio can be fed into the device as analog signal, or in digital form in I2S-bus format.

PCI audio and video broadcast decoder SAA7134HL

7.6 Video processing

7.6.1 ANALOG VIDEO INPUTS The SAA7134HL provides five analog video input pins:

• Composite videosignals (CVBS), from tuner orexternal source

• S-video signals (pairs of Y-C), e.g. from camcorder

• DTV/DVB ‘low-IF’ signal, from an appropriate DTV or

combi-tuner.

Analog anti-alias filters are integrated on chip and therefore, no external filtersare required. The device also contains automatic clamp and gain control for the video input signals, to ensure optimum utilization of the ADC conversion range. The nominal video signal amplitude is 1 V (p-p) and the gain control can adapt deviating signal levels inthe rangeof +3 dB to −6 dB. Thevideo inputsare digitized by two ADCs of 9-bit resolution, with a sampling rate of nominal 27 MHz (the line-locked clock) for analog video signals.

7.6.2 VIDEO SYNCHRONIZATION AND LINE-LOCKED CLOCK

The SAA7134HL recovers horizontal and vertical synchronization signals from the selected video input signal, even under extremely adverse conditions and signal distortions. Such distortions are ‘noise’, static or dynamic echoes from broadcast over air, crosstalk from neighbouring channels or power lines (hum), cable reflections,time baseerrorsfrom videotapeplay-back and non-standard signal levels from consumer type video equipment (e.g. cameras, DVD).

The heart of this TV synchronization system is the generation of the Line-Locked Clock (LLC) of nominal 27 MHz, as defined by ITU-R BT.601. The LLC ensures orthogonal sampling, and always provides a regular pattern of synchronization signals, that is a fixed and well defined number of clock pulses per line. This is important for further video processing devices connected to the peripheral videoport (pins GPIO).It isvery effective torun under the LLC of 27 MHz, especially for on-board hardware MPEG encoding devices, since MPEG is defined on this clock and sampling frequency.

7.6.3 VIDEO DECODING AND AUTOMATIC STANDARD

DETECTION

The SAA7134HL incorporates colour decoding for any analog TV signal. All colour TV standards and flavours of NTSC, PAL,SECAM and non-standardsignals (VCR) are automaticallyrecognized anddecoded intoluminance and chrominance components, i.e. Y-CB-CR, also known as YUV.

The video decoder of the SAA7134HL incorporates an automatic standard detection, that does not only distinguish between 50 and 60 Hz systems, but also determines the colour standard of the video input signal. Various preferences (‘look first’) for automatic standard detection can be chosen, or a selected standard can be forced directly.

7.6.4 ADAPTIVE COMB FILTER The SAA7134HL applies adaptive comb filter techniques

to improve the separation of luminance and chrominance components in comparisonto the separation by achroma notch filter, as used in traditional TV colour decoder technology. The comb filter compares the signals of neighbouring lines, taking into account the phase shift of the chroma subcarrier from line to line. For NTSC the signalfrom threeadjacent linesareinvestigated, andinthe event of PAL the comb filter taps are spread over four lines.

Comb filtering achieves higher luminance bandwidth, resulting in sharper picture anddetailed resolution. Comb filtering further minimizes colour crosstalk artifacts, which would otherwise produce erroneous colours on detailed luminance structures.

The comb filter as implemented in the SAA7134HL is adaptive in two ways:

• Adaptive to transitions in the picture content

• Adaptive to non-standard signals (e.g. VCR).

The integrated digital delay lines are always exactly correct, due to the applied unique line-locked sampling scheme (LLC). Thereforethe comb filter does not needto be switched off for non-standard signals and remains operating continuously.

7.6.5 MACROVISION DETECTION The SAA7134HL detects if the decoded video signal is

copy protected by the Macrovision system. The detection logic distinguishes the three levels of the copy protection as defined in rev. 7.01, and are reported as status information. The decoded video stream is not effected directly, but application software and Operation System (OS) has to ensure, that this video stream maintains tagged as ‘copy protected’, and such video signal would leave the system onlywith the reinforced copy protection. Themulti-level Macrovisiondetection onthe videocapture side supports proper TV re-encoding on the output point, e.g. by Philips TV encoders SAA712x or SAA7102.

7.6.6 VIDEO SCALING

The SAA7134HL incorporates a filter and processing unit to downscaleor upscale thevideo picture inthe horizontal and vertical dimension, and in frame rate (see Figs 11 and 12). The phase accuracy of the re-samplingprocess is1⁄64ofthe originalsample distance. This is equivalent to a clock jitter of less than 1 ns. The filter depthof theanti-alias filteradapts to thescaling ratio, from 10 tapshorizontally forscaling ratiosclose to 1 : 1,to up to 74 taps for an icon sized video picture.

Most video capture applications will typically require for downscaling.But somezooming isrequiredfor conversion of ITU sampling to square pixel (SQP), or to convert the 240 lines of an NTSC field to 288 lines to comply with CCITT video phone formats.

Alternatively, the two programming pages can be applied to support two video destinations or applications with different scaler settings, e.g. firstly to capture video to CPU for compression (storage, video phone), and secondly to pre-view the picture on the monitor screen. A separate scaling region is dedicated to capture raw VBI samples, with a specific sampling rate, and be written into its own DMA channel.

7.6.7 VBI DATA

The Vertical Blanking Interval (VBI) is often utilized to transportdata overanalog video broadcast.Such datacan closely relateto theactual videostream, or justbe general data (e.g. news). Some examples for VBI data types are:

• Closed Caption (CC) for the hearing impaired (CC, on line 21 of first field)

• Intercast data [in US coded in North-American Broadcast Text System (NABTS) format, in Europe in World Standard Teletext (WST)], to transmit internet related services,optionally associated withactual video program content

• Teletext, transporting news services and broadcast related information, Electronic Program Guide (EPG), widely used in Europe (coded in WST format)

• EPG, broadcaster specific program and schedule information, sometimeswith proprietary coding scheme (pay service), usually carried on NABTS, WST, Video Programming Service (VPS), orproprietary data coding format

• Video Time Codes (VTC) as inserted in camcorders e.g. use for video editing

• Copy Guard Management System (CGMS) codes, to indicate copy protected video material, sometimes combined with format information [Wide Screen Signalling (WSS)].

Thisinformation iscoded inthe unusedlines ofthe vertical blanking interval, between the vertical sync pulse and the active visible video picture. So-called full-field data transmission is also possible, utilizing all video lines for data coding.

The SAA7134HL supports capture of VBI data by the definition of a VBI region to be captured as raw VBI samples, that will be sliced and decoded by software on the host CPU. The raw sample stream is taken directly from theADC and is notprocessed or filteredby the video decoder. The samplingrate of raw VBI canbe adjusted to the needs of the data slicing software.

7.6.8 SIGNAL LEVELS AND COLOUR SPACE

Analog TV video signalsare decoded into itscomponents luminance and colour difference signals (YUV) or in its digital form Y-CB-CR. ITU-R BT.601 defines 720 pixels

alongthe line(corresponding toa samplingrate of27 MHz divided by two), and a certain relationship from level to number range (see Fig.13).

The video components do not use the entire number range, but leave some margin for overshoots and intermediate values during processing. For the raw VBI samples there is no official specification how to code, but it is common practice to reserve the lower quarter of the number range for the sync, and to leave some room for overmodulation beyond the nominal white amplitude (see Fig.14).

The automatic clamp and gain control at the video input, together with the automatic chroma gain control of the SAA7134HL, ensures that the video components stream at the output comply to the standard levels. Beyond that additional brightness, contrast,saturation and hue control can be applied to satisfy special needs of a given application. The raw VBI samples can be adjusted independent of the active video.

The SAA7134HL incorporates the YUV-to-RGB matrix (optional), the RGB-to-YUV matrix and a three channel look-up table in between (see Fig.15). Under nominal settings, the RGB space will use the same number range as definedby theITU andshown in Fig.13afor luminance, between 16 and 235. As graphic related applications are based on full-scale RGB, i.e. 0 to 255, the range can be stretchedby applyingappropriate brightness,contrast and saturation values. The look-up table supports gamma correction (freely definable), and allows other non-linear signal transformation such as black stretching.

The analog TV signal applies a quite strong gamma pre-compensation (2.2 for NTSC and 2.8 for PAL). As computer monitors exhibit a gamma (around 2.5), the difference between gamma pre-compensation and actual screen gamma has to be corrected, to achieve best contrast and colour impression.

The SAA7134HL offers a multitude of formats to write video streams over the PCI-bus: YUV and RGB colour space, 15-bit, 16-bit, 24-bit and 32-bit representation, packed and planar formats. For legacy requirements (VfW) a clipping procedureis implemented,that allowsthe definition of 8 overlay rectangles. This process can alternatively be used to associate ‘alpha’ values to the video pixels.

7.6.9 VIDEO PORT, ITU AND VIP CODES

The decodedand/or scaled video streamcan be captured via PCI-DMA to the system memory,and/or can be made available locally through the video side port (VP), using some of the GPIO pins. Two types of applications are intended:

• Streaming real-time video to a video side port at the VGA card, e.g. via ribbon cable over the top

• Feeding video stream to a local MPEG compression deviceon thesame PCIboard, e.g.for timeshift viewing applications.

The video port of the SAA7134HL supports the following 8 and 16-bit wide YUV video signalling standards (see Table 7):

• VMI: 8-bit widedata stream, clocked by LLC = 27 MHz, with discrete sync signals HSYNC, VSYNC and VACTIVE

• ITU-R BT.656, parallel: 8-bit wide data stream, clocked by LLC = 27 MHz, synchronization coded in SAV and EAV codes

• VIP 1.1 and 2.0: 8-bit or 16-bit wide data stream, clocked by LLC = 27 MHz, synchronization coded in SAV and EAV codes (with VIP extensions)

• Zoom Video (ZV): 16-bit wide pixel stream, clocked by LLC/2 = 13.5 MHz, with discrete sync signals HSYNC and VSYNC

• ITU-R BT.601 direct (DMSD): 16-bit wide pixel stream, clocked by LLC = 27 MHz, with discrete sync signals HSYNC, VSYNC/FID and CREF

• Raw DTV/DVB samplestream: 9-bit wide data, clocked with a copy of signal X_CLK_IN.

The VIP standard can transport scaled video and discontinuous datastream by allowing theinsertion of ‘00’ as marker for emptyclock cycles. For the other videoport standards, a data valid flag or gated clock can be applied.

7.7 TV sound

7.7.1 TV SOUND STEREO DECODING

TV soundis modulatedon aninternal soundsubcarrier, on the upper end of the TV RF channel, at 4.5, 5.5, 6.0, or 6.5 MHz, dependingon theTV system. Themodulation is usually on FM and for system L on AM (see Table 14). There are basically three variants how stereo sound is encoded on analog TV transmission:

• An internal multiplexed carrier for the difference signal L − R(BTSC uses AMand EIAJuses FM); thisis similar to FM radio stereo

• A second independent FM carrier in the RF channel (dual FM), that can carry the difference signal L − R, or a second language

• A (second) independent FM/QPSK carrier in the RF channel (NICAM), carrying a digital audio signal, stereo, or dual language mono.

Some parameters of the used coding scheme are modulated on an inaudible pilot carrier.

The SAA7134HL incorporates TV sound decoding from the Sound Intermediate Frequency (SIF) signal. The analog SIF signal is taken from the tuner, digitized and digitally FM or AM demodulated. The pilot tone is

PCI audio and video broadcast decoder SAA7134HL

investigated and the signal is properly stereo decoded. The SAA7134HL supports TV stereo decoding for all NICAM and dual FM sound systems on-chip. The digital FM demodulation maintains stable phase accuracy, resulting into improved channel separation, compared to traditional analog demodulation. BTSC and EIAJ are demodulated to mono-aural sound, but stereo decoding can be added externally.

The SAA7134HL incorporates baseband stereo audio ADCs, to capture sound signals associated with external video sources, e.g. camera, camcorder or VCR.

For concurrent capture of audio and video signals, it is important to maintain synchronization between the two streams. The spoken word and other soundshould match thedisplayed picturewithin avideoframe (1/30s ‘lip-sync’). The SAA7134HL has special means to lock the audio samplingclock tothe videoframe frequency(FLC), sothat a certain fix predefined number of audio samples are associated with each video field. This is especially important for video editing, compression and recording, e.g. time shiftviewing. There is no driftbetween the audio and video streams, not even for longer recording times.

TV sound offers an audio bandwidth of less than 15 kHz, that is usually sampled and digitized with 32 kHz. NICAM as digital sound coding has inherently a 32 kHz sample rate, locked already on the source side to the video rate. The digital audio stream can be captured through dedicated DMA into the PCI memory space, or to the output in I2S-format to further peripheral digital sound processing, e.g. virtual surround sound, or converted to analog stereo via integrated audio DACs, to feed analog audio over the loop back cableto the sound card function.

7.7.2 ANALOG AUDIO PASS-THROUGH AND LOOP BACK

CABLE

Most operating systems are prepared to deal with audio input at only one single entry point, namely at the sound card function. Therefore the sound associated with video has to get routed through the sound card.

The SAA7134HL supports analog audio pass-throughand the loop back cable on-chip. No external components are required. The audio signal, that was otherwise connected to the sound card line-in, e.g. analog sound from a CD-ROM drive, has to be connected to oneof theinputs of the SAA7134HL. By default, after a system reset and without involvement of any driver, this audio signal is passed through to the analog audio output pins, that will feed the loop back cable to the sound card line-in connector. The AV capture driver has to open the default pass-through and switch in the TV sound signal by will.

7.8 DTV/DVB channel decoding and TS capture

The SAA7134HL is optimum equipped to support the application extensionto capture digitalTV signals, e.g. for VSB (ATSC)or DVB (T/C/S).A hybrid TV tunerfor analog and digital TV broadcast receptionusually providesa DTV signal on low IF, i.e. downconverted into a frequency range from0 to 10 MHz. Suchsignals canbe fed toone of the 5 video inputs of the SAA7134HL for digitizing. The digital raw DTV is output at the video port, and is sent to the peripheral channel decoder, e.g. TDA8961 for VSB-8 decoding. The channel decoder provides the sampling clock via the external clock input pin X_CLK_IN (up to 36 MHzinput clockfrequency), andadjusts thesignal gain in the tuner or in the video input path in front of the ADC. Alternatively, the low IF DTV/DVB signal could be fed directly to the channel decoder, depending on the capability for digitizing the selected device.

The peripheral channel decoder circuitry decodes the digital transmission into bits and bytes, apply error correction etc. and outputs a packed Transport Stream (TS) accompaniedby aclock and handshakesignals. The SAA7134HL captures the TS in parallel or serial protocol, synchronized by Start Of Packet (SOP), and pumps it via the dedicatedDMA into the PCI memory space. TheDMA definition supports automatic toggling between two buffers.

7.9 Control of peripheral devices

7.9.1 I

TheSAA7134HL incorporatesan I2C-busmaster toset-up and control peripheral devices such as tuner, DTV/DVB channel decoder, audio DSP co-processors, etc. The I2C-bus interface itselfis controlled from the PCI-buson a command level, reading and writing byte by byte. The actual I2C-bus status is reported (status register) and, as an option, can raise error interrupts on the PCI-bus.

At PCI reset time, the I2C-bus master receives board specificinformation fromthe on-boardEEPROMto update the PCI configuration registers.

The I2C-bus interface is multi-master capable and can assume slaveoperation too. This allowsapplication of the device in the stand-alone mode, i.e. with the PCI-bus not connected. Under the slave mode, all internal programming registers can be reached via the I2C-bus with exception of the PCI configuration space.

7.9.2 PROPAGATE RESET The PCI system reset and ACPI power management

state D3 is propagated to peripheral devices by the dedicated pin PROP_RST. This signal is switched to active LOW by reset and D3, and is only switched HIGH under control of the device driver ‘bywill’. The intention is that peripheral devices will use signal PROP_RST as Chip-Enable (CE). The peripheral devices should enter a low power consumption state if pin PROP_RST = LOW, and reset into default setting at the rising edge.

7.9.3 GPIO The SAA7134HL offers a set of General Purpose

Input/Output (GPIO) pins, to interface to on-board peripheral circuits. These GPIOsare intendedto takeover dedicated functions:

• Digital video port output: 8-bit or 16-bit wide (including raw DTV)

• Digital audio serial output: i.e. I2S-bus output

• Transportstream input:parallelor serial(also applicable

as I2S-bus input)

• Peripheral interrupt input: four GPIO pins of the SAA7134HL canbe enabled to raisean interrupt on the PCI-bus. By thismeans, peripheral devices can directly intercept with the device driver on changed status or error conditions.

Any GPIO pin that is not used for a dedicated function is available for directread and write access via the PCI-bus. Any GPIO pin can be selected individually as input or output (masked write). By these means, very tailored interfacing to peripheral devices can be created via the SAA7134HL capture driver running on Windowsoperating systems.

At system reset (PCI reset) all GPIO pins will be set to 3-state and input, and the logic level present on theGPIO pins at that moment will be saved into a special ‘strap’ register. All GPIO pinshave an internal pull-down resistor (LOW level), but can be strapped externallywith a 4.7 kΩ resistor to the supply voltage (HIGH level). The device driver can investigate the strap register for information about the hardware configuration of a given board.

8 BOUNDARY SCAN TEST

The SAA7134HL hasbuilt-in logic and five dedicatedpins to support boundary scan testing which allows board testing without special hardware (nails).

The SAA7134HLfollows the

TestAccess PortandBoundary -ScanArchitecture”

the Joint Test Action Group (JTAG) chaired by Philips. The 5 special pins are: Test Mode Select (TMS), Test

Clock (TCK), Test Reset (TRST), Test Data Input (TDI) and Test Data Output (TDO).

The Boundary Scan Test (BST) functions BYPASS, EXTEST, SAMPLE, CLAMP and IDCODE are all supported (see Table 15). Details about the JTAG BST-test can be found in the specification “

1149.1”

Description Language (BSDL) description of the SAA7134HL is available on request.

8.1 Initialization of boundary scan circuit

The Test Access Port (TAP) controller of an IC should be in the reset state (TEST_LOGIC_RESET) when the IC is in the functional mode. This reset state also forces the instruction register into a functional instruction such as IDCODE or BYPASS.

To solve the power-up reset, the standard specifies that the TAP controller will be forced asynchronously to the TEST_LOGIC_RESET state by setting pin TRST to LOW level.

8.2 Device identiﬁcation codes

When the IDCODE instruction is loaded into the BST instruction register, the identification register will be connected internallybetween pins TDIand TDO ofthe IC. The identification register will load a component specific code during the CAPTURE_DATA_REGISTER state of the TAP controller and this code can subsequently be shifted out. At board level, this codecan be used to verify component manufacturer, type and version number. The device identification register contains 32 bits, numbered 31 to 0, where bit 31 is the most significant bit (nearest to TDI) and bit 0 is the least significant bit (nearest to TDO); see Fig.16.

A device identification register is specified in

1149.1b-1994”

for the specification of the IC manufacturer, the IC part number andthe IC version number. Itsbiggest advantage is thepossibility to checkfor the correct ICs mounted after production and determination ofthe versionnumber ofICs during field service.

Notes

1. Input leakage currents include high-impedance output leakage for all bidirectional buffers with 3-state outputs.

2. Pins without pull-up resistors must have a 3 mA output current. Pins requiring pull-up resistors must have 6 mA; these are pins FRAME#, TRDY#, IRDY#, DEVSEL#, SERR#, PERR#, INT_A and STOP#.

3. This parameter is to be interpreted as the cumulative edge rate across the specified range, rather than the instantaneous rate at any point within the transition range.

4. REQ# and GNT# are point-to-point signals and have different output valid delay and input set-up times than bused signals. GNT# has a set-up time of 10 ns. REQ# has a set-up time of 12 ns.

5. For purposesof active orfloat timing measurements,the high-impedanceor ‘off’ stateis defined tobe when thetotal current delivered through the device is less than or equal to the leakage current specification.

6. RST is asserted and de-asserted asynchronously with respect to CLK.

7. All output drivers floated asynchronously when RST is active.

8. V

DD(I2C)

9. Nominal analog video input signal is to be terminated by 75 Ω that results in 1 V (p-p) amplitude. This termination resistor should be split into 18 Ω and 56 Ω, and the dividing tap should feed the video input pin, via a coupling capacitor of 47 nF, to achieve a control range from −3 dB (attenuation) to +6 dB (amplification) for the internal automatic gain control. See also the application notes of the SAA7130HL/34HL.

10. See user manuals SAA7130HL/34HL for Anti-Alias Filter (AAF).

11. Definition of levels and level setting: a) The full-scale level for analog audio signals VFS= 0.8 V (RMS). The nominal level at the digital crossbar switch

is defined at −15 dB (FS).

b) Nominal audio input levels: external, mono, Vi= 280 mV (RMS); −9 dB (FS).

12. The analog audio inputs(pins LEFT1, RIGHT1, LEFT2 and RIGHT2) are supported bytwo input levels: 1 V (RMS) and 2 V (RMS), selectable independently per stereo input pair, LEFT1, RIGHT1 and LEFT2, RIGHT2.

14. The NICAMvalues arein accordancewith the EBUspecification. Audioperformance is limitedby thedynamic range of theNICAM 728 system. Due to companding,the quantization noiseis never lowerthan −62 dB with respect tothe input level.

13 SOLDERING

13.1 Introduction to soldering surface mount

packages

Thistext givesa very briefinsight toacomplex technology. A more in-depth account of soldering ICs can be found in our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011). There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for certainsurface mountICs,but itis notsuitable forfine pitch SMDs. In these situations reflow soldering is recommended.

13.2 Reﬂow soldering

Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied tothe printed-circuitboard byscreen printing,stencillingor pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method.

Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 220 °C for thick/large packages, and below 235 °C for small/thin packages.

13.3 Wave soldering

Conventional single wave soldering is not recommended forsurface mountdevices(SMDs) orprinted-circuit boards with a high component density, as solder bridging and non-wetting can present major problems.

To overcome these problems the double-wave soldering method was specifically developed.

If wave soldering isused the following conditions must be observed for optimal results:

• Use a double-wave soldering method comprising a turbulent wavewith high upward pressurefollowed by a smooth laminar wave.

• For packages with leads on two sides and a pitch (e): – larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the printed-circuit board.

The footprint must incorporate solder thieves at the downstream end.

• Forpackages withleadson foursides, thefootprint must be placedat a 45° angleto the transport directionof the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners.

During placementand beforesoldering, thepackage must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured.

Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.

13.4 Manual soldering

Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage(24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C.

When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C.

Notes

1. Formore detailedinformation onthe BGA packagesrefer tothe

“(LF)BGAApplication Note

”(AN01026); ordera copy

from your Philips Semiconductors sales office.

2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporizationof the moisture in them (the so called popcorn effect). Fordetails, refer to the Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit boardand the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface.

4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners.

5. Wave solderingis suitable forLQFP, TQFP andQFP packages witha pitch (e)larger than 0.8 mm;it is definitelynot suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

6. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
