3-2.2 Description
u
D/A Converter
M62393 is a 8-channel 8 bit voltage output digital to analog
latch circuit and gain change circuit of output amplifiers. It
generates reference voltage to D/A converter & PLL phase
adjustment voltage.
u
R/G/B Pre-Driver
The CXA2111R is a signal processor IC developed for LCD
panel, Gamma correction, gain and bias, etc., can be adjusted
using I
2
C bus and external adjustment pins.
u
Timing Generator
The PLSI1016 is a timing signal generator. It provides several
kinds of control signal timing like as line inverter amplifier,
uniformity improvement signal, clamp control and H/V shift
register pulse, for XGALCD panel LCX023 and CXA2111R/
CXA2112R use.
u
Sample and Hold Driver
The CXA2112R is a driver IC developed for use in the 6-
input/12-input Sony Poly-silicon TFT LCD panel. It has a line
invert amplifier and analog de-multiplexers, timing generator
and output buffers required for these.
u
ADC (VGA signal)
It supports display resolutions of up to 1280*1024 (SXGA)
at 75Hz. The AD9884 includes an in1.25V reference,
PLL to generate a pixel clock from HSYNC, and
programmable gain, offset, and clampcircuits. Pixel clock
output frequencies range from 20 to 140MHz. When the
COAST signal is presented, the PLL maintains its output
frequency in the absence of HSYNC. This device is fully
programmable via a two-wire serial port.
u
YUV Decoder
Its automatic detection of 50/60Hz field frequency, and
automatic switching between standards PAL and NTSC. The
SAA7114 is a combination of a two-channel analog
preprocessing circuit including Source-Selection, Anti-Aliasing
Filter and A/D-converter.
