188.8.131.52. xN Clock Bonding Scenario
The following figure shows a xN bonding example supporting 10 lanes. Each lane is running at 12.5 Gbps. The first six TX channels reside in one transceiver bank and the other four TX channels reside in the adjacent transceiver bank. The ATX PLL provides the serial clock to the master CGB. The CGB then provides parallel and serial clocks to all of the TX channels inside the same bank and other banks through the xN clock network.
Because of xN clock network skew, the maximum achievable data rate decreases when TX channels span several transceiver banks.
