Abstract
One embodiment relates to a method of calibrating duty cycle distortion. A data rate of a physical layer interface is changed from a lower rate to a higher rate, and a data rate of one or more transceivers associated with the physical layer interface is changed from the lower rate to the higher rate. An electrical idle state is maintained after changing the data rate of the transceiver. Duty cycle distortion calibration for one or more transceivers associated with the physical layer interface is then performed during the electrical idle state. Other embodiments and features are also disclosed.
