Low latency multi-protocol retimers
Abstract:
A multi-protocol retimer apparatus and method for using the same are disclosed. In one embodiment, an apparatus for performing retiming between first and second devices according to a plurality of protocols comprises: a receiver operable to receive data; a transmitter to transmit data; a first data path coupled to the receiver and the transmitter and operable to transfer data received from the receiver to the transmitter during protocol specific training, where the first data path comprises control circuitry to control protocol specific training of one or both of the transmitter and receiver in response to an indication of one protocol of the plurality of protocols; and a second data path coupled to the receiver and the transmitter, the second data path having a lower latency than the first data path and for use in transferring data received from the receiver to the transmitter after protocol specific training.
