Abstract
Circuits and methods are described which reduce waiting time jitter at a synchronizer/multiplexer by using a “sub-bit” comparison of a clock associated with an unsynchronized data stream and a clock associated with a synchronized data stream to generate a threshold level for use in determining when to stuff bits into the synchronized data stream. The term “sub-bit” means that the phase difference, as measured by, for example, the location of pointers associated with the two clocks, is precise to a fraction of a bit.
