Abstract
A hub port in a hub which preferably eliminates the transfer of jitter in the signal transmitted to an attached node port. In one implementation, jitter transfer is preferably eliminated by transmitting data to an attached node port using a local clock internal to the hub rather than a clock signal recovered from the datastream. The hub port includes smoothing circuits to synchronize data received from the attached node port to the local clock.
