A = 0 - 70°C; VDD = 3.3 V +/-5%; CL =5pF, RS=22 (unless specified otherwise.)
1Guaranteed 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)
5 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#.
