problems with ad9283

Hello,

 

I am using 2 AD9283 in my board.

One of them is working fine.

In other i have some peculiar problem.

Whatever might be the input, D6 to D0 are always identical and D7 always inverse to it.

This happens even if the input pins are detached from PCB pad. (Hence the input is only noise).

 

Sampling frequency is 45 MHz.

Please let me know why this happens.

Are there any problems with board layout?

Is it picking up some stray clock signals?..

 

Thanks and Regards,

Ajith
