Abstract
A method and circuit are provided for synchronizing a first circuit and a second circuit. The first and second circuits are signaled to each generate respective waveform outputs. A phase difference is determined between the generated waveform output from the first and second circuits. A clock of the first circuit and/or second circuit is adjusted by an amount corresponding to the determined phase difference. In response to the phase difference being less than a threshold value, the first and second circuits are signaled to begin normal operation.
