(1)

propagation delay and minimum skew, data input edge rates should be equal to or faster than 1ns/V; control signals equal to or faster

than 3ns/V. In general, the faster the input edge rate, the better the AC performance.

(2)

Propagation delays are specified by design and characterization.

(3)

(4)

Chip to Chip skew is the difference in differential propagation delay between any channels of any devices, either edge.

(5)

Channel to Channel skew is the difference in driver output or receiver output propagation delay between any channels within a device,

common edge.
