5 – 3
IC6341
FPGA
RH-iXC029WJQZQ
This is an FPGA (Field Programmable Gate Array) IC.
In this unit, it performs phase difference absorption of ODD/EVEN of the video 
input signal, I2C slave address conversion, and identification of the pulse drive 
system.
F2
IC6342
PROM
RH-iXC030WJQZQ
This is a PROM (Programmable Read Only Memory) IC.
This IC stores the program contents of FPGA (IC6341).
F2
IC5801
FRC
RH-iXB857WJZZQ
This is an FRC (Field Rate Converter) IC.
This IC supports the vertical frequency at double speed of 120Hz and reduces 
afterimages.
F3
IC6001
IC6002
IC6003
128M-SDRAM
RH-iXB822WJQZQ
This IC is 128-Mbit GDDR SDRAM (Graphic Double Data Rate Synchronous 
DRAM), providing a memory for image processing and buffering OSD data.
In this unit, it stores a frame of two screens and intermediate processing informa-
tion for forming interpolation images.
F4
IC6004
Termination-
REG
RH-iXA361WJZZY
This is a termination linear regulator IC for DDR-SDRAM.
This IC incorporates a high-speed operation amplifier providing excellent 
response against load variation.
The output stage can provide continuous load current of 1.5A and supports varia-
tion peak of maximum 3A.
F4
IC6211
IC6212
LVDS-
Transmitter
VHiTLVD1023-1Q
This is an LVDS (Low-Voltage Differential Signaling) transmitter IC.
This transmitter is designed to support Single Link transmission between Host 
and Flat Panel Display up to 1080p resolutions and Dual Link transmission 
between Host and Flat Panel Display up to QXGA resolutions.
This IC converts 67bits of CMOS/TTL data into LVDS (Low Voltage Differential 
Signaling) data stream.
F5
IC4802
IC4803
Chopper REG
RH-iXA552WJZZY
This is a PWM chopper regulator IC.
This IC is equipped with the output voltage ON/OFF function, overcurrent shut-
down function, overheat protection function, standby low power consumption 
function, and soft start circuit.
In this unit, it forms a 2.5V regulator circuit.
F6
IC4801
DC/DC-CONV
VHiTPS40055-1Y
This is a DC/DC converter IC.
In this unit, it forms a 1.2V regulator circuit.
The TPS4005x is a family of high-voltage, wide input (8 V to 40 V), synchronous, 
step-down converters. The TPS4005x family offers design flexibility with a variety 
of user programmable functions, including soft-start, UVLO, operating frequency, 
voltage feed- forward, high-side current limit, and loop compensation. current 
limit, and loop compensation.
