Abstract
Aspects of the invention include a driver arranged at a stand-alone receiver that is configured to receive a binary sequence from a pseudorandom binary sequence (PRBS) generator arranged at the receiver. The driver is configured to adjust the signal characteristics of the binary sequence to simulate channel loss at the receiver. The driver is further configured to output the adjusted binary sequence to a downstream data path of the receiver to enable the receiver to perform a self-test.
