Digital video encoder SAA7128AH; SAA7129AH

7 FUNCTIONAL DESCRIPTION

The digital video encoder encodes digital luminance and colour difference signals into analog CVBS, S-video and simultaneously RGB or CR-Y-CB signals. NTSC-M, PAL-B/G, SECAM and sub-standards are supported.

Both interlaced and non-interlaced operation is possible for all standards.

The basic encoder function consists of subcarrier generation, colour modulation and insertion of synchronization signals. Luminance and chrominance signals are filtered in accordance with the standard requirements of

“RS-170-A”

and

“ITU-R BT.470-3”

For ease of analog post filtering, the signals are twice oversampled with respect to the pixel clock before digital-to-analog conversion.

The total filter transfer characteristics are illustrated in Figs 8 to 13. The DACs for Y, C and CVBS are realized with full 10-bit resolution; 9-bit resolution for RGB output. TheCR-Y-CBtoRGB dematrixcan be bypassed optionally in order to provide the upsampled CR-Y-CB input signals.

The8-bit multiplexed CB-Y-CRformatsare

“ITU-R BT.656”

(D1 format) compatible, but the SAV and EAV codes can be decoded optionally, when the device is operated in slave mode. Two independent data streams can be processed, one latched by the rising edge of LLC1, the other latched by the falling edge of LLC1. The purpose of that is e.g. to forward one of the data streams containing both video and On-Screen Display (OSD) information to the RGB outputs, and the other stream containing video only to the encoded outputs CVBS and S-video.

For optimum display of RGB signals through a euro-connector TV set, an early composite sync pulse (up to 31 LLC1 clock periods) can be provided on the CVBS output.

VPS data for program dependent automatic startand stop of such featured VCR’s is loadable via I2C-bus.

The IC also contains closed caption and extended data services encoding (line 21), and supports anti-taping signalgeneration in accordancewithMacrovision.It is also possible to load data for copy generation management system into line 20 of every field (525/60 line counting).

A number of possibilities are provided for setting different video parameters, such as:

• Black and blanking level control

• Colour subcarrier frequency

• Variable burst amplitude, etc.

During reset (RESET = LOW) and after reset is released, all digital I/O stages are set to input mode and the encoder is set to PAL mode and outputs a ‘black burst’ signal on CVBS and S-video outputs, while RGB outputs are set to their lowest output voltages. A reset forces the I2C-bus interface to abort any running bus transfer.

7.1 Versatile fader Important note: whenever the fader is activated with the

SYMP bit set to a logic 1 (enabling the detection of embedded Start of Active Video (SAV) and End of Active Video (EAV)), codes 00H and FFH are not allowed within the actual video data (as prescribed by

“ITU-R BT.

656”, anyway). If SAV (00H) has been detected, the fader automatically passes 100% of the respective signal until SAV will be detected.

Within the digital video encoder, two data streams can be faded against each other; these data streams can be input to the double speed MPEG port, which is able to separate two independent 27 MHz data streams MPA and MPB via a cross switch controlled by EDGE1 and EDGE2.

As a further alternative, the VBS and C outputs may provide a second and third CVBS signal.

Itis alsopossible to connecta Philips digitalvideo decoder of the SAA711x family to the SAA7128AH; SAA7129AH. Via the RTCI pin, connected to RTCO of a decoder, information concerning actual subcarrier, PAL-ID and definite subcarrier phase can be inserted.

The device synthesizes all necessary internal signals, colour subcarrier frequency and synchronization signals from that clock.

Wide screen signalling data can be loadedvia the I2C-bus and is inserted into line 23 for standards using 50 Hz field rate.

7.1.1 CONFIGURATION EXAMPLES Figures 4 to 7 show examples on how to configure the

fader between the input ports and the outputs, separated into the composite (and S-video) encoder and the RGB encoder.

7.1.1.1 Conﬁguration 1

Input MPAcan be faded into MPB. The resulting output of the fader is then encoded simultaneously to composite (and S-video) and RGB output (RGBIN = ENCIN = 1). In this example, either MPA or MPB could be an overlay (menu) signal to be faded smoothly in and out.

7.1.2 PARAMETERS OF THE FADER Basically, there are three independent fade factors

available, allowing for the equation:

Output FADEx ln1×()1 FADEx–()ln2×[]+= Where x = 1, 2 or 3 Factor FADE1 is effective, when a colour in the data

stream fed to the MPEG port fader input is recognized as being between KEY1L and KEY1U. That means, the colour is not identified by a single numeric value, but an upper and lower threshold in which a 24-bit YUV colour space can be defined. FADE1 = 00H results in 100% signal at the MPEG port fader input and 0% signal at the fader Videoport input. Variation of 63 steps is possible up to FADE1 = 3FH, resulting in 0% signal at the MPEG port fader input and 100% signal at the fader Video port input.

Factor FADE2 is effective, when a colour in the data stream fed to the MPEG port fader input is recognized as being between KEY2L and KEY2U. FADE2 is to be seen in conjunction with a colour that is defined by a 24-bit internal Colour Look-Up Table (CLUT). FADE2 = 00H results in 100% of the internally defined LUT colour and 0% signal at the fader Video port input. Variation of 63 stepsis possibleupto FADE2 = 3FH,resulting in0%of the internally defined LUT colour and 100% signal at the fader Video port input.

Finally, factor FADE3is effectivewhen acolour inthe data stream fed to the MPEG port fader input is recognized as neither being between KEY1L and KEY1U nor being between KEY2L and KEY2H. FADE3 = 00H results in 100% signal at the MPEG port fader input and 0% signal at the fader Video port input. Variation of 63 steps is possible up to FADE3 = 3FH, resulting in 0% signal at the MPEG port fader input and 100%signal atthe fader Video port input.

Optionally, all upper and lower thresholds can be ignored, enabling to fade signals only against the LUT colour.

If bit CFADM is set HIGH, all data at the MPEG port fader are faded against the LUT colour, if bit CFADV is set HIGH,all dataatthe Videoportfader arefadedagainst the LUT colour.

7.3 Encoder

7.3.1 VIDEO PATH The encoder generates out of Y, U and V baseband

signals luminance and colour subcarrier output signals, suitable for use as CVBS or separate Y and C signals.

Luminance is modified in gain and in offset (latter programmable in a certain range to enable different black level set-ups). A blanking level can be set after insertion of a fixed synchronization pulse tip level in accordance with standard composite synchronization schemes. Other manipulations used for the Macrovision anti-taping process such as additional insertion of AGC super-white pulses (programmable in height) are supported by the SAA7128AH only.

In order to enable easy analog post filtering, luminance is interpolated from a 13.5 MHz data rate to a 27 MHz data rate, providing luminance in 10-bit resolution. Thetransfer characteristics of the luminance interpolation filter are illustrated in Figs 10 and 11. Appropriate transients at start/end of active video and for synchronization pulses are ensured.

Chrominance is modified in gain (programmable separately for U and V), standard dependent burst is inserted, before baseband colour signals are interpolated from a 6.75 MHz data rate to a 27 MHz data rate. One of the interpolation stagescan bebypassed, thusproviding a higher colour bandwidth, which can be made use of for Y and C output. The transfer characteristics of the chrominance interpolation filter are illustrated in Figs 8 and 9.

Theamplitude, beginningand ending ofthe insertedburst, is programmable in a certain range that is suitable for standard signals and for special effects. Behind the succeeding quadrature modulator, colour in a 10-bit resolution is provided on the subcarrier.

The numeric ratio between Y and C outputs is in accordance with the respective standards.

7.2 Data manager

In the data manager, alternatively to the external video data, a pre-defined colour look-up table located in this block can be read out in a pre-defined sequence (8 steps per active video line), achieving a colour bar test pattern generator without the need for an external data source.

7.3.2 TELETEXT INSERTION AND ENCODING Pin TTX receives a WST or NABTS teletext bitstream

sampled at the LLC clock. Two protocols are provided:

• At each rising edge of output signal (TTXRQ) a single

teletext bit has to be provided after a programmable delay at input pin TTX

• Thesignal TTXRQ performsonlya single LOW-to-HIGH

transition and remains atHIGH levelfor 360,296 or 288 teletext bits, depending on the chosen standard.

Phase variant interpolationis achievedon thisbitstream in the internal teletext encoder, providing sufficient small phase jitter on the output text lines.

TTXRQ provides a fully programmable request signal to the teletext source, indicating the insertion period of bitstream at lines which are selectable independently for both fields. The internal insertion window for text is set to 360 (PAL-WST), 296 (NTSC-WST) or 288 (NABTS) teletext bits including clock run-in bits. The protocol and timing are illustrated in Fig.23.

7.3.3 VIDEO PROGRAMMING SYSTEM (VPS) ENCODING Five bytes of VPS information can be loaded via the

I2C-bus and will be encoded in the appropriate format into line 16.

7.3.4 CLOSED CAPTION ENCODER Using this circuit,data inaccordance withthe specification

of closed caption or extended data service, delivered by the control interface, can be encoded (line 21). Two dedicated pairs of bytes (two bytes per field), each pair preceded by run-in clocks and framing code, are possible.

Theactual line numberwheredata is tobeencoded in, can be modified in a certain range.

The data clock frequency is in accordance with the definition for NTSC-M standard 32 times horizontal line frequency.

DataLOW at theoutputof the DACscorresponds to 0 IRE, data HIGH at the output of the DACs corresponds to approximately 50 IRE.

It is also possible to encode closed caption data for 50 Hz field frequencies at 32 times horizontal line frequency.

7.3.5 ANTI-TAPING (SAA7128AH ONLY) For more information contact your nearest Philips

Semiconductors sales office.

7.4 RGB processor

This block contains a dematrix in order to produce red, green and blue signals to be fed to a SCART plug.

Before Y, CBand CR signals are de-matrixed, individual gain adjustment for Y and colour difference signals and 2 times oversampling for luminance and 4 times oversampling for colour difference signals is performed. The transfer curves of luminance and colour difference components of RGB are illustrated in Figs 12 and 13.

7.5 SECAM processor

SECAM specific pre-processing is achieved by a pre-emphasis of colour difference signals (for gain and phase see Figs 14 and 15).

A baseband frequency modulator with a reference frequency shifted from 4.286 MHz to DC carries out SECAM modulation in accordance with appropriate standard or optionally wide clipping limits.

Afterthe HF pre-emphasis,alsoapplied on aDCreference carrier (anti-Clochefilter; see Figs 16 and 17),line-by-line sequential carriers with black reference of 4.25 MHz (Db) and 4.40625 MHz (Dr) are generated using specified values for FSC programming bytes.

Alternating phase reset in accordance with SECAM standard is carried out automatically. During vertical blanking, the so-called “bottle pulses” are not provided.

7.6 Output interface/DACs

In the output interface, encoded Y and C signals are converted from digital-to-analog in a 10-bit resolution. Y and C signals are also combined to a 10-bit CVBS signal.

The CVBS output occurs with the same processing delay (equal to 82 LLC clock periods, measured from MP input to the analog outputs) as the Y, C and RGB outputs. Absolute amplitude at the input of the DAC for CVBS is reduced by15⁄16 with respect to Y and C DACs to make maximum use of conversion ranges.

Red, green and blue signals are also converted from digital-to-analog, each providing a 9-bit resolution.

Outputs of the DACs can be set together via software control to minimum output voltage (approximately 0.2 V DC) for either purpose. Alternatively, the buffers can be switched into 3-state output condition; this allows for a ‘wired AND’ configuration with other 3-state outputs and can also be used as a power-save mode.

Digital video encoder SAA7128AH; SAA7129AH

7.7 Synchronization

The synchronization of the SAA7128AH; SAA7129AH is able to operate in two modes; slave mode and master mode.

In master mode (see Fig.19), the circuit generates all necessary timings in the video signal itself, and it can provide timing signals at the RCV1 and RCV2 ports. In slavemode, itacceptstiming informationeitherfrom the RCV pins or from the embedded timing data of the ITU-R BT.656 data stream.

For the SAA7128AH; SAA7129AH, the only difference between master and slave mode is that it ignores the timing information at its inputs in master mode. Thus, if in slave mode, any timing information is missing, the IC will continue running free without a visible effect. But there must not be any additional pulses (with wrong phase) because the circuit will not ignore them.

In slave mode (see Fig.18), an interface circuit decides, which signal is expected at the RCV1 port and which information is taken from its active slope. The polarity can be chosen. If PRCV1 is logic 0, the rising slope will be active.

The signal can be:

• A Vertical Sync (VS) pulse; the active slope sets the

vertical phase

• An odd/even signal; the active slope sets the vertical

phase, the internal field flag to odd and optionally sets the horizontal phase

• A Field Sequence (FSEQ) signal; it marks the first field

of the 4 (NTSC), 8 (PAL) respectively 12 (SECAM) field sequences. In addition to the odd/even signal, it also setsthe PAL phaseandoptionallydefines the subcarrier phase.

In slave mode, the horizontal trigger phase can be programmed to any point in the line, the vertical phase from line 0 to line 15 counted from the first serration pulse in half line steps.

Whenever synchronization information cannot be derived directly from theinputs, theSAA7128AH; SAA7129AH will calculate it from the internal horizontal, vertical and PAL phase. This gives good flexibility with respect to external synchronization, but the circuit does not suppress illegal settings. In such an event, the odd/even information may vanish as it does in the non-interlaced modes.

In master mode, the line lengths are fixed to 1728 clocks at 50 Hz and 1716 clocks at 60 Hz. To allow non-interlaced frames, the field lengths can be varied by ±0.5 lines. In the event of non-interlace, the SAA7128AH; SAA7129AH does not provide odd/even information and the output signal does not contain the PAL ‘Bruch sequence’.

At the RCV1 pin the IC can provide:

• A Vertical Sync(VS) signalwith 2.5 (50 Hz)or 3 (60 Hz) lines duration

• An odd/even signal which is LOW in odd fields

• A Field Sequence (FSEQ) signal which is HIGH in the

first field of the 4, 8 respectively 12 field sequences.

At the RCV2 pin, there is a horizontal pulse of programmable phase and duration available. This pulse can be suppressed in the programmable inactive part of a field, giving a composite blank signal.

The directions and polarities of the RCV ports can be chosen independently. Timing references can be found in Tables 52 and 60.

7.8 Clock

On the RCV2 port, the IC can provide a horizontal pulse withprogrammable startand stop phase;this pulsecan be inhibited in the vertical blanking period to build up, for example, a composite blanking signal.

The horizontal phase can be set via a separate input RCV2. In the event of VS pulses at RCV1, this is mandatory.It is alsopossible to setthesignal path toblank via this input.

From the ITU-R BT.656 data stream, the SAA7128AH; SAA7129AH decodes only the start of the first line in the odd field. All other information is ignored and may miss. If this kind of slave mode is active, the RCV pins may be switched to output mode.

The input to LLC1 can either be an external clock source or the buffered on-chip clock XCLK. The internal crystal oscillator can be run with either a 3rd-harmonic or a fundamental crystal frequency.

The I2C-bus interface is a standard slave transceiver, supporting 7-bit slave addresses and 400 kbits/s guaranteed transfer rate. It uses 8-bit subaddressing with an auto-increment function. All registers are write and readable, except one read only status byte.

The I2C-bus slave address is defined as 88H with pin 21 (SA) tied LOW and as 8CH with pin 21 (SA) tied HIGH.

The RGB, respectively CR-Y-CB path features a gain setting individually for luminance (GY) and colour difference signals (GCD).

Reference levels are measured with a colour bar, 100% white, 100% amplitude and 100% saturation.

colour difference signals can be compensated by independent gain control setting, while gain for luminance is set to predefined values, distinguishable for 7.5 IRE set-up or without set-up.

9.1 Explanation of RTCI data bits

1. The HPLL increment is not evaluated by the SAA7128AH; SAA7129AH.

2. The SAA7128AH; SAA7129AH generates the subcarrier frequency from the FSCPLL increment if enabled (see item 7.).

3. The PAL bit indicates the line with inverted (R − Y) component of colour difference signal.

4. If the reset bit is enabled (RTCE = 1; DECPH = 1; PHRES = 00), the phase of the subcarrier is reset in each line whenever the reset bit of RTCI input is set to logic 1.

5. Ifthe FISEbit is enabled(RTCE = 1; DECFIS = 1), the SAA7128AH; SAA7129AH takes this bit instead of the FISE bit in subaddress 61H.

6. Iftheodd/even bit is enabled(RTCE = 1;DECOE = 1), the SAA7128AH; SAA7129AH ignores its internally generated odd/even flag and takes the odd/even bit from RTCI input.

7. If the colour detection bit is enabled (RTCE = 1; DECCOL = 1) and no colour was detected (colour detection bit = 0), the subcarrier frequency is generated by the SAA7128AH; SAA7129AH. In the other case (colour detection bit = 1) the subcarrier frequency is evaluated out of FSCPLL increment.

If the colour detection bit is disabled (RTCE = 1; DECCOL = 0), the subcarrier frequency is evaluated out of FSCPLL increment, independent of the colour detection bit of RTCI input.

9.2 Teletext timing

Time tFD is the time needed to interpolate input data TTX and insert it into the CVBS and VBS output signal, such that it appears at t

= 9.78 µs (PAL) or t

TTX

= 10.5 µs (NTSC) after the leading edge of the horizontal synchronization pulse.

Time tPD is the pipeline delay time introduced by the source that is gated by TTXRQ in order to deliver TTX data. This delay is programmable by register TTXHD. For every active HIGH state at output pin TTXRQ, a new teletext bit must be provided by the source (new protocol) or a window of TTXRQ going HIGH is provided and the number of teletext bits, depending on the chosen teletext standard, is requested at input pin TTX (old protocol).

Sincethe beginningofthe pulsesrepresentingthe TTXRQ signal and the delay between the rising edge of TTXRQ and valid teletext input data are fully programmable (TTXHS and TTXHD), the TTX data is always inserted at the correct position after the leading edge of outgoing horizontal synchronization pulse.

Time t

is the internally used insertion window for

i(TTXW)

TTX data; it has a constant length that allows insertion of 360 teletextbits at atextdata rate of6.9375 Mbits/s(PAL), 296 teletextbitsat a textdatarateof 5.7272 Mbits/s (WST) or 288 teletext bits at a text data rate of 5.7272 Mbits/s (NABTS).The insertionwindowis notopened if thecontrol bit TTXEN is logic 0.

Using appropriate programming, all suitable lines of the odd field(TTXOVS and TTXOVE) plus all suitable lines of the even field (TTXEVS and TTXEVE) can be used for teletext insertion.

12 SOLDERING

12.1 Introduction to soldering surface mount packages

Thistext gives averybrief insight toa complex 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 mount ICs,butit is notsuitablefor fine pitch SMDs. In these situations reflow soldering is recommended.

12.2 Reﬂow soldering

Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied tothe printed-circuitboardby screenprinting,stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing.

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 270 °C depending on solder paste material. The top-surface temperature of the packages should preferably be kept:

• below 225 °C (SnPb process) or below 245 °C (Pb-free

process) – for all BGA, HTSSON-T and SSOP-T packages – for packages with a thickness 2.5 mm – for packages with a thickness < 2.5 mm and a

volume ≥ 350 mm3 so called thick/large packages.

• below 240 °C (SnPb process) or below 260 °C (Pb-free

process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages.

Moisture sensitivity precautions, as indicated on packing, must be respected at all times.

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

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

• Use a double-wave soldering method comprising a turbulent wavewith high upwardpressure followed bya 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 with leadsonfour sides, thefootprintmust be placedat a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners.

During placement and before soldering, the package 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 of the leads in the wave ranges from 3 to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively.

A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.

12.4 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.

12.3 Wave soldering

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

Notes

1. Formore detailed informationon the BGApackages refer tothe

“(LF)BGAApplication Note

”(AN01026); order acopy

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 vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the

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

3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account

be processed through morethan one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible.

4. 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 board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface.

5. 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.

6. Wave soldering is suitable for LQFP, TQFPand QFP packages with apitch (e) larger than 0.8 mm;it is definitely not

suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP 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.

8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted

on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request.

9. Hot bar or manual soldering is suitable for PMFP packages.
