[1] MAJOR IC INFORMATIONS
1. General ICs Information

Ref No. Name Part Code Description
KD890FM (MAIN UNIT)
IC1905 1 HDMI-Receiver VHISII9021+-1Q The SiI9021 is a second generation panel Link Cinema receiver that is compatible with the
HDMI 1.1 (High Definition Multimedia interface) specification.
The SiI9021 is capable of receiving and outputting two channel digital audio at up to 192KHz
- an excellent solution for Digital TVs.
The feature of this IC is as follows.
1) Digital video interface supports video processors:
2) Analog RGB and YPbPr output: 10-bit DAC.
3) Digital audio interface supports high-end audio systems:
IC2701 2 4CH- VHITVHC153T-1Y This IC is a super high speed CMOS 4-channel multiplexer using the CMOS technology and
MULTIPLEXER incorporates 2 circuits.
The input consists of 2 addresses A, B, 4 channel inputs C0-C3 and strobe input G, and the
signal of the channel selected by the address input sent as the output Y.
The strobe input is used for prohibition of data output.
That means, when G input is "H" the output becomes "L" unconditionally.
In this model, this IC operates the switch of H/V-SYNC on each signal condition.
IC3002 3 VIDEO RH-IXB624WJN1Q The VCT 6wxyP family is based on functional blocks contained and approved in existing
PROCESSOR products like VCT49xxl, VSP 94x5B, and DPS 94xxA.
That is, the following 6 major functions are included:
1) Audio Processing
2) Video Processing
3) Motion Adaptive Upconversion
4) Scaling, Display Processing and FPD
5) Unified memory for Audio, Video and Text Control, 3D Combfilter PC
Connectivity
6) Controlling, OSD and Text
IC3003 3 Microcontroller RH-IXB664WJZZY This IC is based on LCD Driver and nano Watt Technology and is RISC microprocessor to
control peripheral functions necessary for the system configuration.
In this equipment, the R/C LED on the AVC side and system on the display side are con-
trolled.
IC2301 5 RS232C VHIISL83220-1Y This IC is a line driver receiver in conformity with EIA/TIA-232-E (former RS-232C) standard.
Transmitters/ By connecting a PC, the system can be controlled externally.
Receivers
IC1710 6 CPLD RH-IXB823WJZZQ This IC is a CPLD of Altera and use CMOS EEPROM cells to implement logic
functions with 64 Macrocells. This device controls ON/OFF power supply and
signals for inverter unit.
IC1706 6 Stepdown VHIMP1410ES-1Y The MP1410 is a monolithic step down switch mode regulator with a built in internal power
Converter MOSFET.
In this model, it is assumed 1.8V DC/DC-CONVERTER and is used.
IC3001 E2PROM VHIBR24L64F-1Y The BR24L64F is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable.
This IC saves adjustment values of the adjustment process mode, etc.
The data is given out by commands from the main microprocessor.
IC1901 E2PROM VHI24LC2BIN-1Y This IC is a 2-wire (I2C bus type) serial EEPROM this is electrically
programmable.
This EEPROM chip stores EDID data of the input for HDMI.
This data is controlled by the I2C signal.
IC2303 E2PROM VHIBR24C21F-1Y This IC is a 2-wire (I2C bus type) serial EEPROM this is electrically
programmable.
This EEPROM chip stores EDID data of the input for PC.
This data is controlled by the I2C signal.
KD604FM (AV UNIT)
IC301 Sound Amp VHITDA8931T-1Y The TDA8931 is a switching power stage for high efficiency class-D audio power amplifier
IC302 systems.
With this amplifier a compact 1x 20 W closed loop self-oscillating digital amplifier system can
be built.
In this model, Audio amplifier is 10watt.
KD605FM (POWER UNIT)
IC705 Switching VHIMR4020++-1 This IC is a power supply for the switching regulator on the primary side.
Regulator Overvoltage/overcurrent protection circuit, other protection circuits and control circuits are
built in this IC.
