11.4.1. 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, and Pixel oriented characters (DRCS).
The 8-bit Microcontroller runs at 360 ns. cycle time (min.). 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.

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 an 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 dedica ted pin. A Rising edge or Falling
edge strobe transmitter will interoperate with a Falling edge strobe Receiver (DS90CF386/DS90CF366)
without any translation logic.

11.17. AL875
11.17.1. General Description
The AL875 is a high-speed triple 8-bit monolithic analog-to-digital converter (ADC) designed for digitizing
RGB graphics/video signal or other applications. Its 110 MHz conversion rate can support display
resolution of up to 1280x1024 at 60Hz refresh rate. The AL875 accepts 0.6~2.0V analog input range
without using pre-amplifiers which may reduce the overall S/N ratio. Digitized data is piped at the full clock
rate to the 24-bit output port. The AL875 uses 3.3V power with 5V tolerant I/O and low power dissipation.
The sampling clock is provided by an external clock source, usually a PLL, which multiplies the frequency
of the input reference clock (usually a HSYNC signal) to generate the sampling clock. The AL875 provides
a programmable PLL divider up to 4096. In addition, the input active horizontal and vertical starting and
ending positions can be detected to ensure that the whole picture fits into the displayable region of the
screen. Through an I2C interface, the AL875 is fully programmable to support various graphic resolutions.

11.19. ICS1523
11.19.1. Description
The ICS 1523 is a low-cost but very high-performance frequency generator for line-locked and genlocked
high-resolution video applications. Using ICS ’s advanced low-voltage CMOS mixed-mode technology, the
ICS 1523 is an effective clock solution for video projectors and displays at resolutions from VGA to beyond
UXGA. The ICS 1523 offers pixel clock outputs in both differential (to 250 MHz) and single-ended (to 150
MHz) formats. Dynamic Phase Adjust™ circuitry allows user control of the pixel clock phase relative to the
recovered sync signal. A second differential output at half the pixel clock rate enables deMUXing of
multiplexed analog-to-digital converters. The FUNC pin provides either the regenerated input from the
phase-locked loop (PLL) divider chain output or a re-synchronized and sharpened input HSYNC. The
advanced PLL uses either its internal programmable feedback divider or an external divider. The device is
programmed by a standard I2C-bus™ serial interface and is available in a 24-pin small-outline integrated
circuit (SOIC) package.
11.19.2. Features
• Pixel clock frequencies up to 250 MHz
• Very low jitter
• Dynamic Phase Adjust (DPA) for clock outputs
• Balanced PECL differential outputs
• Single-ended SSTL_3 clock outputs
• Double-buffered PLL/DPA control registers
• Independent software reset for PLL/DPA
• External or internal loop filter selection
• Uses 3.3 Vdc. Inputs are 5 V-tolerant.
• I2C-bus™ serial interface can run at either low speed (100 kHz) or high speed (400 kHz).
• Lock detection
• 24-pin 300-mil SOIC package

11.22. MSP34X0G
MSP3400G
Multistandard Sound Processor Family
11.22.1. 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 functional 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 selection
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 (two channels per line, 2*16 bits) per sampling cycle
(32 kHz) are transmitted.
2. I2S_DA_OUT: For output, two channels (2*16 bits) 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.
11.22.2. Features
• Standard Selection with single I2C transmission
• Automatic Standard Detection of terrestrial TV standards
• Automatic Sound Selection (mono/stereo/bilingual), new registers MODUS, STATUS
