A method and system for modeling and calibrating duty cycle distortion (DCD) of a Serializer and Deserializer (SerDes) device, including first generating a clock DCD signal. Once the clock DCD signal is generated, it is calibrating based upon results obtained from a filtering process of the ...
[DCDrms,DCDpkpk] = jitterDutyCycle(x,y,SymbolTime = t) measures the duty cycle distortion (DCD) from input jittery waveform by using the specified symbol time. For PAM2 waveform. DCD captures the component jitter in every other symbol. When generalized to PAMn, DCD can refer to either ...
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...

* The additional 1K resistor across the differential input pins will reduce the duty cycle distortion. * You recommend to have input slew rate of 3V/ns. * Additive jitter and noise floor will degrade at lower slew rates. I have two additional questions. ...
A technique for compensating for duty cycle distortion in an output data signal generated by a synchronous dynamic random access memory device (SDRAM) is provided. The output latch of the SDRAM is driven by an output clock signal generated by a delay lock loop (DLL). The output clock signal...
