Abstract
A transmitter device having a calibrator circuit is disclosed. The calibrator circuit performs duty cycle calibration and phase calibration on a plurality of clock signals of the transmitter device. In one embodiment, the phase calibration is performed based on a comparison of the clock signals to a reference clock signal from the plurality of clock signals. In another embodiment, the calibrator circuit uses fixed patterns of data signals to perform phase calibration on the plurality of clock signals.
