How to encode the data to higher frequency to transmit through fiber link and recover the data on receiver side?

Hi, I m trying to establish a fiber link between two FPGA board (MAX10M08) via a SFP-6 comnet fiber module. I'm using soft LVDS FPGA IP core for serialization and deserialization of the data. My da...

Hi SooY,

Thank You very much for the reply. But unfortunately there is no DPA mode availabe for MAX10 M08.

The LVDS IP available for MAX10 devices is soft LVDS intel FPGA IP. https://www.intel.com/content/www/us/en/programmable/documentation/sam1394433606063.html#sam1394435177990 .

However, there is a data realignment circuit using RX_DATA_ALIGN pulse. Page 26,27. I have tried using it and tried using ISSP tool to pulse the RX_DATA_ALIGN signal (as advised on the link https://www.youtube.com/watch?v=02lgfcxSjQA&list=PLJCQGKgvE0JCr1W9vFL4phkvlPtWHlUVa&index=4&t=0s) but still no luck. The received signal as captured is

I'm stuck here. Just don't know how to recover the data correctly, it should be 8-bit continuous counter data.

Any suggestion will be highly appreciated.

Thank you very much.
