Circuit and method for reading data transfers that are sent with a source synchronous clock signal

摘要

A circuit and method for reading data transfers that are sent with a source synchronous clock signal. The circuit has a data input for receiving data signals carrying data being transferred, a clock input for receiving synchronous clock signals, and a delay circuit connected to the clock input for generating a delayed clock signal which is delayed from said synchronous clock signal a predetermined time period. The circuit also includes a pipeline connected to the data input for sampling the data on the data input in response to said delayed clock signal thereby stretching the sampling of incoming data.
