tSKD1 is the magnitude difference in differential propagation delay time between the positive-going-edge and the negative-going-edge of

the same channel.

(2)

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 VDD and within 5°C of each other within the operating temperature range.

(3)

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.

(4)

fMAX generator input conditions: tr = tf < 1 ns (0% to 100%), 50% duty cycle, differential (1.05V to 1.35 peak to peak). Output criteria:

60%/40% duty cycle, VOL (max 0.4V), VOH (min 2.4V), load = 15 pF (stray plus probes). The parameter is ensured by design. The limit

is based on the statistical analysis of the device over the PVT range by the transition times (tTLH and tTHL).
