摘要:
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 clock DCD signal. Once the clock DCD signal is calibrated, a data DCD signal is generated and calibrated based upon results obtained from a filtering process of the data DCD signal.
