TIMING DIAGRAM
= 3.3V 10% or 2.5V 5%; T
Measured with 400mV input signal, 50% duty cycle, all outputs loaded with 50 to V
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
than the specified peak-to-peak jitter value.
