Data interface with delay locked loop for high speed digital to analog converters and analog to digital converters

摘要

A system comprises a first circuit includes a data transmitter circuit that transmits digital data based on a first clock signal. A sync generator outputs a sync signal based on the first clock signal. A digital to analog converter circuit includes a data receiver circuit that latches the digital data based on a second clock signal. A digital to analog converter core receives an output of the data receiver circuit. A delay locked loop circuit determines a delay based on the second clock signal and the sync signal and outputs the first clock signal to the first circuit based on the second clock signal and the delay.
