Video
Controller Part.
This part amplifies the level of video signal for the digital
conversion and converts from the analog video signal to the
digital video signal using a pixel clock.
The pixel clock for each mode is generated by the PLL.
The range of the pixel clock is from 25MHz to 135MHz.
This part consists of the Scaler, ADC convertor, TMDS receiver and LVDS
transmitter.
The Scaler gets the video signal converted analog to digital, interpolates
input to 1280 X 1024 resolution signal and
outputs 8-bit R, G, B signal to transmitter.
Power
Part.
This part consists of the one 3.3V, and one 1.8V regulators to
convert power which is provided 5V in Power board.
12V is provided for inverter, 5V is provided for LCD panel.
Also, 5V is converted 3.3V and 1.8V by regulator. Converted power is provided
for IC in the main board.
The inverter converts from DC12V to AC 700Vrms and operates back-light lamps of
module.
MICOM
Part.
This part is include video controller part. And this part
consists of EEPROM IC which stores control data, Reset IC and
the Micom.
The Micom distinguishes polarity and frequency of the H/V sync are supplied
from signal cable.
The controlled data of each modes is stored in EEPROM.
SERVICE
mode
