* 4MHz reference frequency input [signal from phase-locked loop (PLL) tuning system] or operating as crystal
oscillator.
* VIF Automatic Gain Control (AGC) detector for gain control operating as a peak sync detector for negative
modulated signals and as a peak white detector for positive modulated signals.
IC 202: COFDM DECODER.
Part number: STV0360C
Sharp code: RH-IXB682WJZZQ
The STV0360C is a COFDM ( codec orthogonal frequency division multiplex) demodulator that performs IF to MPEG-
2 block processing of OFDM carriers. It is intended for digital terrestrial receivers for compressed video, sound
and data services. It implements all the functions from the tuner IF output to the MPEG-2 transport stream input. The
STV0360C integrates an A/D converter that delivers the required performance to handle up to 64 QAM
carriers in a direct IF sampling architecture.
IC204: I2C BUS SELECTOR (TUNER CONTROLLED FROM VCTP OR COFDM DECODER).
Part number: SN74LV4053APWR
Sharp code:
VHILV4053AT-1Y
The SN74LV4053APWR is a high-speed CMOS analog multiplexer/demultiplexer backed by silicon gate CMOS tech-
nology. The multiplexer function includes the selection and mixing of analog and digital signals. The chip include two
independent 3 channels selectors. A digital signal through the control terminal turns on the switch of a corresponding
channel.
KD628WJ (DIGITAL UNIT):
IC4001: DIGITAL PROCESSOR MPEG 1/2 DECODER (Audio/Video).
Part number: STI5516AUCL
Sharp code:
RH-IXB680WJZZQ
The STi5516 is a device that integrates all of the back-end functions required for mainstream set-top boxes . These
include:
An enhanced ST20 32-bit RISC CPU with a 166MHz clock, 8Kbytes of instruction cache, 8Kbytes of data cache and
8Kbytes of embedded SRAM.
A 16-bit, 133MHz Shared Memory Interface, with support for 64- and 128-bit confi gurations.
A programmable External Memory Interface supporting six separately confi gurable banks of SRAM, Flash and
DRAM.
An MPEG-2 (MP@ML) decoder, including trick modes such as smooth fast-forward and rewind.
A Graphics/Display unit with fi ve display panes, alpha blending, antialiasing and antifl utter fi lters, subpicture decoder,
and display compositor with separate OSD (On-Screen Display) controls for TV and VCR outputs.
PAL/NTSC/SECAM encoder.
Audio subsystem with embedded DSP for all popular audio formats.
A full range of on-chip peripherals, including fi ve UARTs, six parallel I/O banks, two smart card interfaces, four PWM
channels, teletext serializer, multi-channel IR transmitter/receiver, and a modem analog front-end interface.
IC 4203: 16 Mbit Flash Memory (Program Memory).
Part number: MBM29LV160BE70TN
Sharp code:
RH-IXA964WJN1
IC 4201 & IC 4202: 64Mbit SDRAM (Temporary Data).
Part number: KAS641632H-UC75
Sharp code: RH-IXB076WJZZQ
IC4204: NVM 64Kb-E2PROM FOR DIGITAL PROCESSOR (IC4001).
Part number: BR24L64F
Sharp code:
VHIBR24L64F-1Y
The BR24L64F is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable. This IC stores all data
related to the Digital Module (Channels, User settings, etc.).
IC4003: RESET ICs FOR DIGITAL PROCESSOR (IC4001).
Part number: BU4228G
Sharp code: VHIBU4228G+-1Y
Low voltage detector IC with adjustable output delay. Standard detection voltage = 2.8V.
