ADV7513 - No video output signal

Question asked by SonNguyen on Oct 22, 2015
Latest reply on Jan 22, 2016 by GuenterL


I'm facing an issue with ADV7513. Here is my configuration:

INPUT VIDEO (from camera):

-Full HD 1920x1080,  30FPS.

-Video format YCrCb 4:2:2

-20 bits data


OUTPUT VIDEO (expectation)

- Full HD, 30FPS

- Video format YCrCb 4:4:4

- 20bits data


I saw many threads in this forum and followed all the answers but none of them work for me.

My current configuration for ADV7513 is based on this thread No video output from ADV7513


My sequence for configuration (based on

1) "ADV7511 Power up defaults"

2) run scripts 6-1fx (for 1080i@30) to display an image setting the pixel bus to YCbCr 444.

3) run one of the script to put the system into the required sync mode (1080i30 20-bit bus embedded syncs).

I'm using PIC24F08KL301 to configure ADV7513 through I2C. Currently, I can read and write data to ADV7513 registers. I can saw the I2C data on oscilloscope.

I checked the input signal on ADV7513 pins, I could see some signal on those pins but when I checked the output pins, there was nothing there.


At the beginning I used  only embedded sync mode, then I tried with separate syncs mode, until I read the thread (I mentioned above) I configured ADV7513 with embedded mode with syncs adjustment, but all configuration didn't work for me.


I checked the signal on HSYNC, VSYNC and DE pin on my camera module, Here a pic for what I got:

Red is HSYNC

Green is VSYNC

Blue is DE



Does my configuration have something wrong?

Or does my hardware need to change something to make it works? (Attached is my schematic)
