About ADV7183 Video Decoder Chip.

Started by mall...@yahoo.co.in November 5, 2008
Hi!

Iam having a custom board which contains BF532,ADV7183B and ADV7171 as main components..It's schematic has taken from EZ kit lite...

Iam facing a problem when i am capturing a frame(Code is same as given VisualDSP directory "Video Input" little bit modified for our board) by using Our Board...

As soon as i have applied the Power Supply to the board..,the LLC1 and LLC2 of adv7183 are started to generate the clock,irrespective of whether there is any input video or not..........generally these has to be generated based on the video Line frequency...and in Ezkit lite i have checked it is not the case

The Video frame what i have captured is all dark.............

i don't know what's the problem...............
any suggestions
