More Information
Summary:A port of a computing device includes multiple receiver-transmitter pairs, each of the receiver-transmitter pairs including a respective receiver and a respective transmitter. The device further includes state machine logic that detects a training sequence received by a particular one of the receiver-transmitter pairs on a particular lane from a tester device. The training sequence includes a value to indicate a test of the particular receiver-transmitter pair by the tester device. The particular receiver-transmitter pair enters a first link state in association with the test and one or more other receiver-transmitter pairs of the port enter a second link state different from the first link state in association with the test to cause crosstalk to be generated on the particular lane during the test.
