Abstract

A low-latency signaling link retimer generates an output signal transmission synchronously with respect to a core clock signal alternately selected from two or more plesiochronous or mesochronous clock sources with switchover between or among the core-clock sources executed without shrinking, extending or otherwise disrupting the edge-to-edge core clock period or clock duty cycle.
