AR# 56078: JESD204B v4.0 - Updated RX Buffer settings for 7 Series FPGA GTX, GTP and GTH
JESD204B v4.0 - Updated RX Buffer settings for 7 Series FPGA GTX, GTP and GTH
The RX Buffer can sometimes indicate an underflow on RXBUFSTATUS as the buffer full level drops below the underflow threshold. The buffer does not always completely empty and cause data errors, but the buffer settings should be updated to improve reliability and prevent the possibility of underflow.
Update the following GTX, GTP and GTH settings to ensure there is enough space in the buffer to prevent underflow:
