5.6.7.1.1. Differential Data Orientation
There is a set relationship between an external clock and the incoming data. For operations at 1 Gbps and a serialization factor of 10, the external clock is multiplied by 10. You can set phase-alignment in the PLL to coincide with the sampling window of each data bit. The data is sampled on the falling edge of the multiplied clock.
