Duty-cycle distortion and specifications for jitter test-signal generation

Duty-cycle distortion is one of the causes of deterministic jitter. Clarification and refinement of this jitter type is presented here. The jitter-tree is then updated with the jitter types discussed. Predicting the behavior of electrical systems under stress from jitter through simulations is limited by the availability of signal sources with controllable and flexible jitter properties in the design environment. A jitter specification method for ISI and DCD is recommended.
