Abstract
A network switch includes first and second clock-and-data-recovery (CDR) circuits, a cross-bar switch to couple the first and second CDR circuits, and a first test pattern generation circuit electrically coupled with the first CDR circuit. The first test pattern generation circuit is configured to generate a test pattern and transmit the test pattern from the first CDR circuit to the second CDR circuit via the cross-bar switch. The network switch also includes a first test pattern checking circuit, electrically coupled with the second CDR circuit, to verify the test pattern received at the second CDR circuit.
