GTH transceiver - received data error correction

Hello,

 

I'm using GTH transceiver for high speed transfer. I want to know if there is any way to correct error at the receiver end or resend data again.

Using IP as a continuous stream flow by implementing PRBS. 

How transmission packet formation looks like in GTH transceiver?

Thank you

Error correction and data re-transmit is not part of GTH PMA/PCS features. Please see also UG576.
These features should be implemented in data-link protocol/layer (instead of PHY/Coding layer).
(i.e: PCIe IP is implementing all these mechanisms in its module. It is not using GTH features )

It depends on your GTH configuration, whether your encoding/decoding configuration is using 8B/10B, 64B/66B, RAW (or other).
Generate GTH example design and run simulation is a good method to find the answer.


Thanks & regards
