1. 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 165MHz.
This part consists of the Scaler, ADC and TMDS receiver .
The Scaler gets the video signal converted analog to digital, interpolates input to 1920 x 1200 resolution signal and
outputs 8-bit R, G, B signal to transmitter.
2. Power Part.
This part consists of the 3.3V and 1.8V regulator to convert power which is provided 5V,
5V in Power board and Micom
5V is provided for LCD panel.(W2600H-PFS)
12V is used for LPL LCD Panel Power.(W2600HP-BNS)
3. MICOM Part.
This part consists of EEPROM IC which stores control data 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.
*refer to the each frequency of crystal oscillators and working frequency.
Video processor : 14.31818MHz.
USB Hub : 30MHz
LVDS Clock Freq. : 154MHz
MEMORY Clock Freq. : 183MHz
