3.5. 10GBASE-R PHY Performance and Resource Utilization for Arria V GZ and Stratix V Devices
Because the 10GBASE-R PHY is implemented in hard logic in Arria V GZ and Stratix V devices, it uses less than 1% of the available ALMs, memory, primary and secondary logic registers.
The following table lists the total latency for an Ethernet packet with a 9600 byte payload and an inter-packet gap of 12 characters. The latency includes the number of cycles to transmit the payload from the TX XGMII interface, through the TX PCS and PMA, looping back through the RX PMA and PCS to the RX XGMII interface. (Stratix V Clock Generation and Distribution illustrates this datapath.)
