An integrated circuit (IC) chip is provided. The IC chip includes a signal output via which an outgoing signal is transmitted, and a signal input via which an incoming data signal is received. Also included on the IC ship is a pass circuit to couple the signal output to the signal input during testing of the IC chip. Furthermore, a delay circuit produces a first timing signal and a second timing signal during testing of the IC chip. The second timing signal is delayed from the first timing signal according to a test parameter. The first timing signal triggers transmission of a test signal via the signal output, and the second timing signal triggers sampling of the received test signal via the signal input. |
