Strobe signal management to clock data into a system

摘要

A method of communicating with a source synchronous device can include determining an expected number of pulses of a strobe signal to be received in response to a first read request directed to the source synchronous device and receiving the strobe signal from the source synchronous device. Pulses in the strobe signal can be counted. Responsive to detecting a last pulse of the expected number of pulses of the strobe signal, the strobe signal can be replaced with a reference signal that is phase and frequency aligned with the strobe signal.
