[1] MAJOR IC INFORMATIONS
1. MAJOR IC INFORMATIONS
1.1. IC1504 (VHiSii9387+-1Q)
This IC is 5 input and 1 output HDMI port processor.
The TMDS cores run at 2.25Gbps. (Supports video resolutions up to 1080p, 60Hz, 12bit.)
The adaptive equalizer provides long cable support.
This IC has been pre-programmed with HDCP keys.
EDID and DDC support for 5 HDMI/DVI ports and 1 VGA port. (This IC includes 512-byte NVRAM and 256-byte SRAM for 5 HDMI ports and 128-byte
SRAM for VGA port.)
This IC supports the mandatory and several optional 3D formats described in the HDMI 1.4 Specification.
“Audio Return Channel” and “HDMI Ethernet Channel” support for one receiver port.
When changing this IC, please write EDID (how to write EDID is shown in Chapter 5 and section 10.1).
1.2. IC2001 (RH-iXD241WJN1Q: LC-60LE632U, RH-iXD241WJNBQ: LC-70LE732U)
The monitor microprocessor is intended to communicate with the main microprocessor and to operate the system.
It also controls power of the entire system.
1.3. IC2703 (VHiYDA164BZ-1Y)
The Class-D type digital audio power amplifier YDA164BZ gives maximum continuous output of 10 W/ch.
1.4. IC3303 (RH-iXD220WJQZQ)
This LSI is FULL HIGH-DEFINITION 1080P DIGITAL TV SYSTEM-ON-A-CHIP.
It combines a transport de-multiplexer, a high definition video decoder, an AC3 audio decoder, a four-link LVDS transmitter, a V-by-One transmitter,
and an NTSC/PAL/SECAM TV decoder with a 3D comb filter (NTSC/PAL).
It supports Full-HD MPEG1/2/4/DiviX/VC1/RM/H.264/AVS video decoder standards, and JPEG.
Audio support includes a BTSC and a Dolby AC3/MPEG-2 Layer 1, 2, audio decoder.
A SPDIF output and a pair of analog outputs (L-R) are provided.
The LSI incorporates a complete ARM11-based microprocessor subsystem including caches with bridging to memory and a local bus, where external
peripherals can be attached.
Integrated peripherals include two USB 2.0, three UARTs, counter/timers and GPIO controllers.
1.5. IC3501, IC3502, IC3503 (RH-iXD226WJQZQ)
These are 1G-bit (64M x 16bit) DDR3-1333 synchronous DRAM.
1.6. IC8401 (RH-iXD287WJQZQ)
The 2G-bit NAND flash memory device stores the main CPU program.
1.7. IC8455 (VHiR24064AS-1Y)
This is 64k-bit EEPROM device including the user setting.
1.8. IC506 (VHiM3221EiP-1Y)
This IC is a high speed, single-channel RS-232 transceiver interface device that operates from a single 3.3V power supply.
The device provides the electrical interface between an asynchronous communication controller and the serial-port connector.
This device operate at data signaling rates up to 460kbit/s.
All RS-232 (Tout and Rin) and CMOS (Tin and Rout) inputs and outputs are protected against electrostatic discharge (up to +/- 15kV ESD protection).
1.9. IC2704 (VHiAK4201EU-1Y)
This IC is audio amplifier for line-out/head-phone.
1.10. IC4405 (VHiMT5112EE-1Q)
This IC is a demodulator for digital terrestrial HDTV(8VSB) and digital CATV(64/256QAM).
It is compliant with ATSC A/53, SCTE DVS-031, and ITU J.83 Annex B standards.
