Hi,

We are using tda2ex custom board with vision sdk 2.12

//setup
soc -> deserialiser(ds90ub926q1) -> serialiser(ds90ub921q1) -> cmos camera sensor

In the above setup 54Mhz cmos camera sensor pclk image streaming properly

when we set cmos camera sensor pclk 80Mhz the image is not proper Below is my 80Mhz output snap.

Kindly give the suggestion.

Hi Raj,

Can you confirm if Camera is actually streaming valid image at 80 MHz? Please check if hSync and vSync is stable from Camera (i.e. no change in frequency)
