1 IC6001 VHiS24CS02J-1Y 2K E2PROM
This IC is 2 K bit 2 wire serial E2PROM. This EEPROM chip stores EDID-data for
HDMI of a display. This data is controlled through I2C signals. It is written in exe-
cuting EDID WRITE on the monitor process adjustment and the 3 page. Please
write in at the time of IC exchange. The harness of LB connector on IF board
(P7908) is making a monitor's size distinction serve a double purpose.
Please write in after attaching the right harness. (The data of EDID changes by
harness classification.)

2 IC6004 VHiSii9181A-1Q HDMI_SW
This IC is IC for HDMI SW.
It is used as an equalizer for waveform shaping of the case where the cable which
is not an enclosed HDMI cable is used, and the sake at the time of 10m cable
(schedule) use of an option.

4 IC6052 VHiTLVD1023-1Q
LVDS
TRANSMIT-
TER
This is LVDS (Low-Voltage Differential Signaling) transmitter IC.

5 IC6201 RH-iXC068WJQZQ
DECODER
& CPU
This IC is DECODER & MAIN CPU. Although the output from STB is 1080p,
when the signal of 480p and 1080i is directly connected to a display, the signal of
480p and 1080i is changed into 1080p by this IC. Moreover, OSD of a display is
generated here and added to a picture signal. Data reading processing is also
performed from a service terminal as a wall picture function here.

7 IC6302 RH-iXB801WJQZY
CLOCK-
GEN
This IC is a clock generator. From a 27MHz crystal oscillator, generation of
54MHz for STC, 33MHz for CPLD, 33MHz for FPGA, and 33MHz for PCI is per-
formed.
