Part Code
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.)

This IC is IC for HDMI SW.
It is used as an equalizer for waveform shaping of the case where the cable which
HDMI_SW
is not an enclosed HDMI cable is used, and the sake at the time of 10m cable
(schedule) use of an option.
This IC is HDMI Receiver IC. A differential signal is input from IC6004, and it con-
HDMI_RX
verts it into 8 bits of RGB of CMOS for each.
LVDS
This is LVDS (Low-Voltage Differential Signaling) transmitter IC.
TRANSMIT-
It convert each 8 bits of RGB of CMOS from IC6102 into a LVDS signal.
TER
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
DECODER
480p and 1080i is changed into 1080p by this IC. Moreover, OSD of a display is
& CPU
generated here and added to a picture signal. Data reading processing is also
performed from a service terminal as a wall picture function here.
Clock Gen-
This IC is a clock generator. From a 27MHz crystal oscillator, generation of
erator
48MHz for SCC, 54MHz for STC, and 74.25MHz for PWM is performed.
This IC is a clock generator. From a 27MHz crystal oscillator, generation of
CLOCK-
54MHz for STC, 33MHz for CPLD, 33MHz for FPGA, and 33MHz for PCI is per-
GEN
formed.
512Mb-
DDR2-
This is a 512Mb DDR2 SDRAM IC. This IC is IC for IrSS encoding.
SDRAM-
It operates as a memory of IC6201 (DECODER).
MEMORY
Ir_communi
This IC is IC for IrSS encoding.
cation con-
It encodes by receiving the signal from the IrSS euphotic part on a RC/LED
troller
board, and data is transmitted to IC6201 through SLOW BUS.
This IC is 64K bit serial E2PROM of 8K word *8K bit configuration.
64K
As for this IC, the data of a portion with which IC6201 (DECODER) is processing
E2PROM
is saved.
64Mb-
The S29GL064A is 64Mb-NOR Flash memory.
FLASH
The software of IC6201 (DECODER) is stored.
This IC is 1 Gb-NAND-FLASH memory.
1Gb-NAND-
The data of IC6201 (DECODER) and the pre-install picture of a wall picture func-
FLASH
tion are stored in this IC.
This IC is CPLD (Complex Programmable Logic Device).
CPLD
By SLOW BUS control signal, the reset signal sent to each device, the extended
I/O port of the control signal etc., and the modulated light signal are generated.
This IC is Audio DSP. This IC is performing delayed audio delay processing of the
S-DSP
picture of IC6201(DECODER), analog 2.1ch processing, and processing of SRS
TruSurroundXT from I2S signal inputted from IC7103(FPGA).
This IC is 1-bit amplifier. A sampling frequency is 12.288MHz. It drives by
1bit-AMP
7.5W+7.5W in all of the 52 types and 65 types.
This IC is a digital audio power amplifier. In this models, it used as woofer for SRS
SUB-P-AMP
TruSurroundXT, and it drives by 15W in 52 and 65 types.
