Hi there,


I am trying to use the ADV7180-32EBZ eval kit to decode analog video from MC-495 CMOS Image sensor into 8 Bit parallel data to connect to the i.MX6 applications processor. The end goal is to connect this to a display of some sort.


As a first step, I connected the camera straight to an analog input on an old TV, and I was able to see the stream.


When I use the ADV7180-ADV7392 bridge from A-D and then D-A (the eval kit has two RCA phono jacks that convert analog to digital and then back to analog) and then connect back to the display, I am not seeing the stream from camera.


The clocks are fine at 28 MHz and all the voltage supplies are fine. The camera outputs NTSC/PAL at ~525TVL.


Am I missing something here? Any inputs would be highly appreciated.
