See Figure 7-2 0.1 0.3 μs tie Time interval error 216 – 1 PRBS data at 100 Mbps 1 ns (1) Also known as pulse skew. (2) tsk(o) is the skew between outputs of a single device with all driving inputs connected together and the outputs switching in the same direction while driving identical loads. (3) tsk(pp) is the magnitude of the difference in propagation delay times between any terminals of different devices switching in the same direction while operating at identical supply voltages, temperature, input signals and loads. 6.16 Switching Characteristics—3.3-V Supply VCC1 = VCC2 = 3.3 V ± 10% (over recommended operating conditions unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tPLH, tPHL Propagation delay time See Figure 7-1 6 11 18.5 ns PWD Pulse width distortion(1) |tPHL – tPLH| 0.5 5.9 ns tsk(o) Channel-to-channel output skew time (2) Same direction channels 4.4 ns tsk(pp) Part-to-part skew time(3) 5 ns tr Output signal rise time See Figure 7-1 0.7 3 ns tf Output signal fall time 0.7 3 ns tDO Default output delay time from input power loss Measured from the time VCC goes below 1.7V.
