Description of A/V(MAIN and SUB PCB) and POWER
4-2-5. DVI(Digital Visual Interface) signal
To process DVI signal, graphic card of AV device reads EDID data from IC101(ROM). Then DVI
signal is directly inputted to IC112, which outputs digital 24bit RGB and H, V. The output goes
through IC140 for digital image processing.
- Main IC
A. IC101: ROM containing EDID data (EDID: display capabilities such as resolution, aspect ratio
etc.)
B. IC112: DVI signal processor (Input: TMDS Output: 24bit digital RGB, H, V)
TP128: SYNC for PLL (output of IC114)
TP127: Output clock (output of IC114)
