Clock Cycle-Cycle Period / Cycle-Cycle Jitter Definition

DspSee Symbol

Active Edge	Clock Cycle-Cycle Period / Cycle-Cycle Jitter
Falling	It is the time difference between two consecutive clock periods. The period in this case is measured from falling edge to falling edge.
Rising	Same as above except that the period in this case is measured from rising edge to rising edge.
Both	Same as above except that the period in this case is measured from rising edge to falling edge and from falling edge to rising edge.

Significance of statistics:
Mean	The mean cycle-to-cycle period (jitter) should be as small as possible. The larger this value is, the more will it result in reduction of timing margins.
Min	Not important.
Max	Very important. The max cycle-to-cycle period (jitter) should be as small as possible. The larger this value is, the more will it result in reduction of timing margins.
Peak cy-cy	Good for understanding the jitter distribution.
Peak-to-peak	Good for understanding the jitter distribution.
