Notes on Electrical Characteristics:
1
Guaranteed by design and characterization, not 100% tested in production.
2
Slew rate measured through Vswing centered around differential zero
3
Vxabs is defined as the voltage where CLK = CLK#
4
Only applies to the differential rising edge (CLK rising and CLK# falling)
Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of CLK and
falling edge of CLK#. It is measured using a +/-75mV window centered on the average cross point where CLK meets CLK#.
