Cyclone V LVDS deserializer bitrate

Hi, I am writing to see if we can identify the reason why the LVDS receiver of our system has problems to receive the incoming stream properly. The incoming stream comes from an LVDS ADC (AD9257) ...

Hi Ivan,

Thanks for answering!

Sorry, I made a mistake. It is 560MHz, the output bitrate of a 14-bit ADC channel sampling at 40MHz. We developed our own PCB and put a lot of effort in matching the lengths of the different LVDS lines.

And yes, with lower bitrates (280Mhz, 448MHz) we were able to receive the bitstream without problems

Cheers and thanks for your help
