AR# 50790: LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-KR) - Using Link Training for 10GBASE-KR on 7 Series Devices
LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-KR) - Using Link Training for 10GBASE-KR on 7 Series Devices
Initial testing has shown that it is most likely not necessary to perform any Link Partner link training. The RX DFE features in the Xilinx transceivers are sufficient for recovery of clock and data in most circumstances. This means that the Training ports on the 10GBASE-KR core can be tied off. Any near-end link training will still take place as described in the IEEE 802.3 standard.
Hardware testing for 10GBASE-KR is still being completed.
