Abstract: Calibration of devices communicating on a shared data bus may improve data integrity on the shared data bus by reducing duty cycle distortion. Duty cycle distortion may be reduced by adjusting timing of a transceiver in a device for communicating on the shared data bus using calibration codes. The calibration codes may be loaded into memory and used to reconfigure the transceiver timing on the shared data bus with reconfiguration occurring within one or more unit-intervals of time. The calibration code may be used, for example, to adjust a PMOS or NMOS trim circuit at the transceiver.
