(1)

All typical values are at 25

°C and with a 3.3-V supply.

(2)

tsk(p) is the magnitude of the time difference between tPLH and tPHL of a specified terminal.

(3)

tsk(o) is the magnitude of the difference in propagation delay times between any specified terminals of channel 2 to 4 of a device when

inputs are tied together.

(4)

tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of channel 2 to 4 of two devices, or

between channel 1 of two devices, when both devices operate with the same source, the same supply voltages, at the same

temperature, and have identical packages and test circuits.

(5)

Jitter specifications are ensured by design and characterization and measured in BER-12
