DESCRIPTION OF BLOCK DIAGRAM
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 148.5MHz in E2350V case(28MHz to 148.5MHz In E2350V CASE).
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 1920 X
1080 resolution signal and outputs 8-bit R, G, B signal to transmitter.
2. Power Part.
This part consists of the one DC-DC converter to convert power which is provided 12V from Adapter.
12V is provided for LED Driver IC, 5V is provided for LCD panel and micom in E2350T case .
Also, 5V is converted 3.3V and 1.2V by dual channel regulator. Converted power is provided for IC in the main board.
The inverter the 12V provided from LED Driver IC converts from DC 12V to DC 44V and operates back-light LED
3. MICOM Part.
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 flash memory.
