Clock Negative Cycle-Cycle Duty Cycle Definition

DspSee Symbol

Active Edge	Clock Negative Cycle-Cycle Duty Cycle
Falling	It is the time difference between two consecutive negative duty cycle measurements.
Rising	- do -
Both	Not Applicable.

Significance of statistics:
Mean	Very important for DDR and dual-strobe systems. A higher mean negative cycle-to-cycle duty cycle will directly result in reduction of timing margins.
Min	Not important.
Max	Very important for DDR and dual-strobe systems. A higher max negative cycle-to-cycle duty cycle will directly result in reduction of timing margins.
Peak cy-cy	Good for understanding the jitter distribution in DDR and dual-strobe systems.
Peak-to-peak	Good for understanding the jitter distribution in DDR and dual-strobe systems.
