IC2710 (NJU26150)
The NJU26150 is a processor IC that is composed of DIR-incorporating 24-bit DSP (Digital Signal Processor)
core and various interfaces. The program written on IC2708 (EEPROM) is downloaded to the built-in PRAM
for operation.
The built-in functions include audio delay, BBE, and parametric equalizer. Digital processing is made in the
I2S format.
There are 3 data input lines (SDI0, SDI1, SDI2) and 3 data output lines (SDO0, SDO1, SDO2). Two different
types of LR clock (LRI, LRO) and BCK (BCKI, BCKO) are used to transfer the data along the serial data line.
∫
IC2700 (NJU26106)
The NJU26106 is a digital signal processor that decodes the matrix-encoded (Lt/Rt) stereo signal. On this set,
the processor is used for Dolby Virtual function.
∫
IC1001 (IXB027WJ)
This IC is a high-performance CPLD (Complex Programmable Logic Device). The device serves to communicate
with the display and also to control the entire system.
∫
IC2004 (IXA870WJ)
The LCD controller microprocessor has many tasks: OSD control on the LCD monitor, thermistor-sensed
panel temperature detection, temperature parameter setting for the QS driver, timing for the liquid crystal
display panel controller, dimmer data setting, power control, power line monitoring, remote control decoding,
and OPC control.
∫
IC3704 (TA1318AF)
This IC is designed to process the TV component signal synchronization and to measure the frequency.
The frequency measurement function for input signals and other functions for synchronized reproduction are
incorporated in a single chip. The chip readily meets the horizontal synchronized reproduction function (15.75
kHz, 31.5 kHz, 33.75 kHz, 45 kHz) and vertical synchronized reproduction function (525I, 525P, 625I, 750P,
1125I, 1125P, PAL 100 Hz, NTSC 120 Hz).
