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 146MHz In W2252TE.  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 1680X1050(W2252TE) 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.
15V is provided for inverter in W2252TE.  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 DC 15V to AC 700Vrms and operates back-light lamps of module in W2252TE.

MICOM Part.
This part is including 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 is supplied from signal cable.  The controlled data of each mode is stored in EEPROM.
