(1)
Measurements are made with the Agilent 81250 ParBert System with a N4872A generator (600 fs tJIT(CLK), 13 ps tJIT(pp)) and a N4873A
analyzer.
(2)
All typical values are at 25
°C and with a 3.3-V supply.
(3)
tsk(p) is the magnitude of the time difference between tPLH and tPHL of a specified terminal.
(4)
tsk(o) is the magnitude of the difference in propagation delay times between any specified terminals of a sink-port bank when inputs of
the active source port are tied together.
(5)
tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals 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.
