Phase optimization for data communication between plesiochronous time domains

摘要

A method and apparatus for optimizing data transfer between launch and capture domains driven by plesiochronous launch and capture clocks transmits a beacon of representational data from the launch domain to the capture domain and captures the beacon in the capture domain using the capture clock. The captured beacon is monitored for an anomaly. If an anomaly is not detected, a phase of the capture clock is adjusted and the beacon is transmitted, captured and monitored until an anomaly is detected. If an anomaly is detected, the phase of the capture clock is optimized relative to the captured beacon.
