We currently have the pre-series of a device employing the ADV7850 as the front-end.
Unfortunately 3 of 12 boards have an unstable output at SXGA60 and at 1280x960/60,
1 board also at SXGA75.
This is regardless if the input is HDMI or VGA, it seems to be a problem of the output PLL
All other resolutions we tested (42) are running w/o problems, even UXGA with 12bit per color.
Could someone please give hints for how we can try other settings (register) for the output
PLL stability ? It makes insecure that some boards have this problem and other not.
Thanks in advance
