Abstract
Consistent with embodiments of the present disclosure, a method involves a redriver circuit with compliance test mode features. A redriver circuit is configured to process received compliance patterns for a compliance test mode. A compliance test mode is detected by a redriver circuit having a first input port and a second input port. The redriver detects the presence of a remote receiver termination on both input ports, monitors both input ports to detect received data and enters compliance test mode in response to no received data being detected on the input ports for a set period of time. Compliance patterns are tracked by monitoring for valid signal levels on the second input port. De-emphasis is controlled on at least one input port in response thereto.
