ABSTRACT:
Methods and apparatuses for calibrating out static timing offsets across multiple outputs of a transmitting device are provided. In accordance with at least one embodiment, a signal is selected as the master reference signal, and a closed-loop feedback system is provided to align one or more outputs of the transmitting device to a master reference signal. The master reference signal can be one of the signals being output by the transmitting device, an internal signal that is representative of the desired placement of the edges, or an external signal received by the transmitting device. The signal from the transmitting device is received by a receiver, and a calibration control block is used to generate a control signal to adjust the operation of the transmitting device.
