CL includes probe and jig capacitance.

All typicals are given for VCC = 3.3 V, TA = 25°C.
3
Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50 , tTLH and tTHL (0% to 100%) ≤ 3 ns for RIN+/RIN.
4
tSKD1 is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel.
5
tSKD3, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same VCC and within 5°C
of each other within the operating temperature range.
6
tSKD4, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended operating
temperature and voltage ranges, and across process distribution. tSKD4 is defined as |maximum minimum| differential propagation delay.
7
fMAX generator input conditions: f = 200 MHz, tTLH =
tTHL < 1 ns (0% to 100%), 50% duty cycle, differential (1.05 V to 1.35 V peak-to-peak). Output criteria: 60%/40% duty
cycle, VOL (maximum 0.4 V), VOH (minimum 2.7 V), load = 15 pF (stray plus probes).
