[MAIN UNIT]
1 IC801 DVP-M2 RH-IXB882WJZZQ
DVP-M2 is 1 chip picture signal processing LSI for flat panel displays
corresponding to a multi-format (NATC/PAL/SECAM). A 10-bit A/D con-
verter is mounted as an analog image input, and it has the input termi-
nal of one CVBS, Y/C, Y/Pb/Pr, one R/G/B input each, and one SCART
input. In a picture signal processing part, a high definition image is
made by three-dimensional adaptation type Y/C separation and motion
adaptation three-dimensional NR conversion. DVP-M 2S builds in 64 M
bit SDRAM as a buffer memory, the microcomputer for system control
(32/16 bit), 1024 K bytes of flash memory, and the sound multiplex
decoder, and constitutes the system from small number of parts.

2 IC803 64Kbit-E2PROM VHIS24CS64A-1Y
The S24CS64A is a 64Kbit-2-wire (I2C bus type) serial EEPROM that is
electrically programmable.
This IC serves to store the adjustment and other data in the adjustment
process mode.
The data is given out by commands from the main microprocessor.
M1
3 IC2001 RESET VHIPST8229N-1Y It used to system reset for sub-micon(IC2002). M2
4 IC2002 Sub_micon RH-IXC165WJZZQ
IXC165WJ is the submicrocomputer added in order to compensate the
shortage of control with DVP-M2 (MAIN-MICON). This IC mounts with
the R8C/Tiny series core. It has the capability to execute a command
at high speed, and high-speed operation processing is possible. More-
over, variegated peripheral equipment, such as a multifunctional timer,
serial interface, and a data flash (1KB * 2 blocks), is built in.
M2
5 IC2003 4Kbit-E2PROM VHIBR24L04F-1Y
The BR24L04F is a 4Kbit-2-wire (I2C bus type) serial EEPROM that is
electrically programmable.
This IC saves the control data such as un uncontrollable control signal
by MAIN-MICON (it builds in IC801) etc.
The data is given out by commands from the sub microprocessor.
M2
6 IC2004 Series regulator VHIPQ1LAX95-1Y This IC generates B3.3V-regurator. M2
7 IC9201 RSDS-transmitter RH-IXC209WJZZQ
IXC209WJ (LR38875) is a RSDS transmitter for LCD controllers. LVDS
RGB 8bit data and a clock signal are changed and outputted to RSDS.
A RSDS output is a differential output of data output 12 pair +CLK out-
put 1 pair, and a data rate corresponds to 180Mbps (@CLK = 90MHz).
Connection with the RSDS panel is enabled by using it between the
LCD panel of a RSDS interface and the LCD timing controllers of a
CMOS output, without changing the existing system.

8 IC9202 OP-AMP *2 VHINJM2904V-1Y
The NJM2902 is an operation amplifier circuit containing 4 circuits
which operates with a single power supply. Operation from split power
supplies is also possible and the low power supply drain is independent
of the magnitude of the power supply voltage. In this machine, it adopts
for the COM-BIAS power supply generation.

9 IC8701 Series regulator VHIPQ025ENA-1Y This IC is 2.5V regulator-IC to drive HDMI-IC. M4
10 IC8702
HDMI-INTER-
FACE
VHIMST3383D-1Q
MST3383MK is HDMI-IC with 1 set of single link inputs. This IC builds in
the function of a HDMI interface (25-170MHz operation and HDMI1.0
are supported), a digital audio interface (a 2ch-serial audio output /
SPDIF digital audio output is supported), and a digital video interface
(ITU601/656 YCbCr output format is supported).
M4
11 IC401 1Kbit-E2PROM VHIBR24C21F-1Y
This IC is a 1Kbit-2-wire (I2C bus type) serial EEPROM this is electri-
cally programmable.
The EEPROM chip stores the EDID data of PC input. This data is con-
trolled through I2C signals.
M5
12 IC403 2Kbit-E2PROM VHIBR24L02F1EY
This IC is a 2Kbit-2-wire (I2C bus type) serial EEPROM this is electri-
cally programmable.
The EEPROM chip stores the EDID data of HDMI input. This data is
controlled through I2C signals.
M5
13 IC1001 OP-AMP *4 VHIBA2902FV-1Y
In this machine, it adopts for liquid crystal panel drive power supply
(VH24, VH56, VL24, and VL56).
M7
14 IC301 A-SELECTOR VHINJM2750M-1Y
NJM2750 is 4 input/1 output stereo audio selector with two.
In this machine, the change of PC-audio, the DVP output audio, and the
HDMI-audio is performed.
