Major IC Informations
1. IC2510 (A385WJ) S/PDIF
This is an audio signal encoder IC that converts signals to the S/PDIF format.
The output signal of this IC is optically connected to an external digital adio device,allowing you to enjoy
digital sound on an LCD TV.
2. IC3202 (A416WJ) MSP
This is an audio signal processing IC called a Multi-Standard Sound Processor.
This IC not only processes the audio signal of all standard analog TV broadcasts worldwide, it also
incorporates the NICAM digital sound standard.
3. IC3301 (CXA2040A) VIDEO-SW
This is an I2S BUS-compliant, 5-input, 3-output video switch.
This switch is used to select the digital tuner output, analog tuner output, composite video input, and S-
terminal input.
4. IC1603 (6258308X) 2Mb-SRAM
This is a 256K x 8 bit CMOS static RAM.
This IC is used to store TELTEXT signals (which are broadcast simultaneously) in the memory.
These signals are output by a command from the TELTEXT micon as necessary.
5. IC1602 (A134WJ) 4M-FLASH
This IC is a 4Mb dual operation flash memory.
It incorporates a TELTEXT micon program, and it outputs data on a command from the TELTEXT micon.
6. IC1601 (SDA5550M) TELETEXT (LC-22AA1M ONLY)
The SDA5550M 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 Signaling (WSS) data
used for PAL plus transmissions (line23).
7. IC3501 (IXA904WJ) MICRO PROCESSOR
This is a 16-bit single chip microcomputer that uses a high-performance silicon gate CMOS process. Although
this microcomputer uses high-functionality commands, it has a high-command efficiency. It has a 1Mbyte
address space and it has the ability to carry out instructions at high speed. It also incorporates an OSD and
a data slicer. This microcomputer supports Closed Captions (an official teletext broadcast standard for
hearing-impaired people) and ID1 (525p compliant).
8. IC801 (VPC3230D) VPC
This IC is an I2S BUS-compliant video processor.
This IC works as a 4H comb filter, Y/C separator, PAL/NTSC/SECAM color decoder, PIP processor, etc. Its
results are output as an 8-bit Y-OUT/CrCb-OUT signal which is supplied to a scaler.
9. IC4601 (FLI2310) SCALER
This IC is an I2S BUS-compliant scaler IC.
The FLI2310 is a highly integrated digital video format converter for DTV and DVD applications using
patented deinterlacing and post-processing algorithms from Faroudja Laboratories, coupled with highly
flexible scaling, a wide variety of aspect ratio conversions, and other special video enhancing features to
produce the highest quality image.
10. IC4603/IC4516 (A312WJ) 64M-SDRAM
This IC is a 64Mb (2M x 32bit) synchronous DRAM memory.
This IC is used to control the progressive converter,format converter (image conversion), noise reducer on
the scaler (IC4601) and LCD control IC (IC4512), and Quick Shoot. Video signal is stored when correcting
the Quick Shooting image quality.
