4. MULTI STANDARD SOUND PROCESSOR
The MSP34x0G family of single-chip Multistandard Sound Processors covers the sound processing of all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on a single chip. These TV sound processing ICs include versions for processing the multichannel television sound (MTS) signal conforming to the standard recommended by t The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is performed alignment free. Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM Stereo Radio standard.

11.5.1. General description
This integrated circuit provides RGB switching allowing connections between peri TV plug, internal RGB generator and video processor in a TV set. The input signal black level is tied to the same reference voltage on each input in order to have no differential voltage when switching two RGB generators. An AC output signal higher than 2 Vpp makes gain going slowly down to 0dBto protect the TV set video amplifier from saturation. Fast blanking output is a logical OR between FB1 (Pin 8) and FB2 (Pin 10).

11.6. TEA6415
11.6.1. General description
The main function of the IC is to switch 8 video input sources on 6 outputs. Each output can be switched on only one of each input. On each input an alignment of the lowest level of the signal is made (bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input and output is
6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an external resistor bridge, 5 V external resistor bridge). All the switching possibilities are changed through the BUS. Driving 75 needs an external transistor. It is possible to have the same input connected to several outputs. The starting configuration upon power on (power supply: 0 to 10V) is undetermined. In this case, 6 words of 16 bits are necessary to determine one configuration. In other case, 1 word of 16 bits is necessary to determine one configuration.

11.8. SDA55XX (SDA5550)
11.8.1. General description
The SDA55XX is a single chip teletext decoder for decoding World System Teletext data as well as Video Programming System (VPS), Program Delivery Control (PDC), and Wide Screen Signalling (WSS) data used for PAL plus transmissions (Line 23). The device also supports Closed caption acquisition and decoding. The device provides an integrated general-purpose, fully 8051-compatible Microcontroller with television specific hardware features. Microcontroller
has been enhanced to provide powerful features such as memory banking, data pointers, and additional interrupts etc. The on-chip display unit for displaying Level 1.5 teletext data can also be used for customer defined on screen displays. Internal XRAM consists of up to16 Kbytes. Device has an internal ROM of up
to 128 KBytes. ROMless versions can access up to 1 MByte of external RAM and ROM. The SDA 55XX supports a wide range of standards including PAL, NTSC and contains a digital slicer for VPS, WSS, PDC, TTX and Closed Caption, an accelerating acquisition hardware module, a display generator for Level 1.5 TTX data and powerful On screen Display capabilities based on parallel attributes The 8-bit Microcontroller runs at 360 ns. cycle time (m
, and Pixel oriented characters (DRCS).
in.). Controller with dedicated hardware does most of the internal TTX acquisition processing, transfers data to/from external memory interface and receives/ transmits data via I2C-firmware user-interface. The slicer combined with dedicated hardware stores TTX data in a VBI buffer of 1 Kilobyte. The Microcontroller
firmware performs all the acquisition tasks (hamming and parity-checks, page search and evaluation of header control bits) once per field. Additionally, the firmware can provide high-end Teletext features like Packet-26-handling, FLOF, TOP and list-pages. The interface to user software is optimized for minimal overhead. SDA 55XX is realized in 0.25 micron technology with 2.5 V supply voltage and 3.3 V I/O (TTL compatible). The software and hardware development environment (TEAM) is available to simplify and speed up the development of the software and On Screen Display. TEAM stands for TVT Expert Application Maker. It improves the TV controller software quality in following aspects: – Shorter time to market – Re-usability – Target independent development – Verification and validation before targeting – General test concept – Graphical interface design requiring minimum programming and controller know how. – Modular and open tool chain,
configurable by customer.

MSP3400G
Multistandard Sound Processor Family
11.17.1. Introduction
The MSP 34x0G family of single-chip Multistandard Sound Processors covers the sound processing of all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on a single chip. Figure shows a simplified func
tional block diagram of the MSP 34x0G. This new generation of TV sound processing ICs now includes versions for processing the multichannel television sound (MTS) signal conforming to the standard recommended by the Broadcast Television Systems Committee (BTSC). The DBX noise reduction, or alternatively, MICRONAS Noise Reduction (MNR) is performed alignment free. Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM Stereo Radio standard. Current ICs have to perform adjustment procedures in order to achieve good stereo separation for BTSC and EIA-J. The MSP 34x0G has optimum stereo performance without any adjustments. All MSP 34x0G versions are pin and software downward compatible to the MSP 34x0D. The MSP 34x0G further simplifies controlling software. Standard se
lection requires a single I²C transmission only. The MSP 34x0G has built-in automatic functions: The IC is able to detect the actual sound standard automatically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can be evaluated internally with subsequent switching between mono/stereo/bilingual; no I²C interaction is necessary (Automatic Sound Selection).
Source Select
I2S bus interface consists of five pins:
1. I2S_DA_IN1, I2S_DA_IN2: For input, four channels (t
wo channels per line, 2*16 bits) per sampling cycle
(32 kHz) are transmitted.
2. I2S_DA_OUT: For output, two channels (2*16 bi
ts) per sampling cycle (32 kHz) are transmitted.
3. I2S_CL: Gives the timing for the transmission of I2S serial data (1.024 MHz).
4. I2S_WS: The I2S_WS word strobe line defines the left and right sample.

11.18. DS90C385
11.18.1. General Description
The DS90C385 transmitter converts 28 bits of LVCMOS/LVTTL data into four LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. Every cycle of the transmit clock 28 bits of input data are sampled and transmitted. At a transmit clock frequency of 85 MHz, 24 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 595 Mbps per LVDS data channel. Using a 85 MHz clock, the data throughput is 297.5 Mbytes/sec. Also available is the DS90C365 that converts 21 bits of LVCMOS/LVTTL data into three LVDS (Low Voltage Differential Signaling) data streams. Both transmitters can be programmed for Rising edge strobe or Falling edge strobe through a dedicated pin. A Rising edge or Falling edge strobe transmitter will interoperate with a Falling edge strobe Receiver (DS90CF386/DS90CF366) wi
thout any translation logic. The DS90C385 is also offered in a 64 ball, 0.8mm fine pitch ball grid array (FBGA) package which provides a 44% reduction in PCB footprint compared to the TSSOP package. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces.

11.19.1. General Description
These P-Channel enhancement mode power field effect transistors are produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process is especially tailored to minimize on-state resistance and provide superior switching performance. These devices are particularly suited for low voltage applications such as notebook computer power management and other battery powered circuits where fast switching, low in-line
power loss, and resistance to transients are needed.
