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,

Well if this is the case, i would recommend you use the LVDS IP on both transmitting and receiving side. You can write your RTL design as well but it would be better if you could leverage the IP.

THank YOu.

Hi ,

Thanks for the suggestion. I have been using LVDS IP on both transmitter and receiver side. But, the system works occasionally only. Sometime there is no reception at all and when there is, the data recovered is not aligned and not in order. I tried with sending a 10 bit counter data and what I receive on the receiver side is random data between 1 to 1023. I was wondering if there is any way to align and recover the data on receiver side and make sure the reception is not occasional.

Thank You
