Note:
1. Data valid tFITDV to GTX_CLK Min Setup time is a function of clock period and max hold time. (Min Setup = Cycle time
– Max Hold)
2. The minimum cycle period (or maximum frequency) of the RX_CLK is dependent on the maximum platform frequency
of the speed bins the part belongs to as well as the FIFO mode under operation. See Section 2.4.6, “Platform to FIFO
Restrictions,” for more detailed description.
