The Clock-Domain-Crossing Conundrum

– Jerry Cox The Clock-Domain-Crossing conundrum is this:  Where is the evidence of Clock-Domain-Crossing (CDC) failures that have occurred during a product’s service life? We know there have been products that have had CDC failures during test and been re-spun,...

A Public Synchronizer

GET THE PUBLIC SYNCHRONIZER NOW You might ask yourself “Why would anyone want to have a public synchronizer available to download?” Usually designers just grab a flip-flop from his or her company’s or a standard cell vendor’s library. However, are these handy...

Measuring Metastability

Measuring metastability is just 50 years old this year. In 1965 my colleague Tom Chaney took a sampling ‘scope picture of an ECL flip-flop going metastable. S. Lubkin had made mention of the phenomenon over a decade before that, but at that time most engineers were...
