16.3
The ports on the two ends of a link must transmit data at a rate that is within 600 parts per million (ppm)
of each other at all times. This is specified to allow bit rate clock sources with a +/– 300 ppm tolerance.

REFCLK cycle time
REFCLK cycle-to-cycle jitter. Difference in the period of any two adjacent
REFCLK cycles
Phase jitter. Deviation in edge location with respect to mean edge location
defines the specifications for the differential output at all transmitters (TXs). The parameters are
