System and method for establishing a known timing relationship between two clock signals

摘要

A system and method for establishing a known timing relationship between two clock signals, wherein a first clock signal is operable to clock data transfer operations from a transmitter domain to a receiver domain and a second clock signal is operable to be transported to the receiver domain. Circuitry is provided for detecting an edge in a global framework clock (GFC) signal that is supplied to the transmitter domain. A common alignment signal is manufactured that is based at least in part upon the GFC signal. A multiplexer and register arrangement is operable to output the second clock signal in response to the common alignment signal which is also used for gating the data transfer operations clocked by the first clock signal.
