Abstract:
In a multi-wire channel that includes at least three wires, each unique wire pair of the multi-wire channel has approximately the same signal propagation time. In this way, jitter can be mitigated in the multi-wire channel for signaling where, for a given data transfer, a differential signal is transmitting on a particular pair of the wires and every other wire is floating. In some implementations, matching of the signal propagation times involves providing additional delay for at least one of the wires. The additional delay is provided using passive signal delay techniques and/or active signal delay techniques.
