Abstract
In an example, a self-testing integrated circuit (IC) includes N channels i and a controller, where i is an integer from 1 to N. Each channel i may include a clock and data recovery circuit (CDR), a pseudorandom bit stream (PRBS) generator circuit, and a PRBS checker and eye quality monitor (EQM) circuit. The controller may be configured to selectively couple the channels i in a daisy chain during self-testing.
