TIMING DIAGRAM
= 2.5V ±5%; T
Measured with 400mV input signal, 50% duty cycle, all outputs loaded with 100ý across each output pair, unless otherwise stated.
Specification for packaged product only.
Skew is measured between outputs under identical transitions.
See “Timing Diagram.”
Cycle-to-cycle jitter definition: the variation in period between adjacent cycles over a random sample of adjacent cycle pairs. T
where T is the time between rising edges of the output signal.
Total jitter definition: with an ideal clock input of frequency - f
the specified peak-to-peak jitter value.
