(1) CL includes probe and jig capacitance.
(2) Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50 Ω, tr and tf (0% to 100%) ≤ 3 ns for RIN.
(3) tSKD1 is the magnitude difference in differential propagation delay time between the positive-going-edge and the negative-going-edge of the same channel.
(4) tSKD2 is the differential channel-to-channel skew of any event on the same device. This specification applies to devices having multiple receivers within the integrated circuit.
(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 the recommended operating temperature and voltage ranges, and across process distribution. tSKD4 is defined as |Max − Min| differential propagation delay.
(7) fMAX generator input conditions: tr = tf < 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 (max 0.4 V), VOH (min 2.7 V), load = 15 pF (stray plus probes).
