Multiprotocol resynchronizer with low latency

摘要

Disclosed are a multiprotocol resynchronizer and a method of using the same. In one embodiment, an apparatus for resynchronizing between a first and a second device according to a plurality of protocols comprises: a receiver operable to receive data, a transmitter to send data, one to the receiver, and the transmitter coupled first data path operable to communicate data received from the receiver to the transmitter during a protocol-specific training, the first data path comprising a control circuitry to perform protocol-specific training of the transmitter and / or in response to an indication of a protocol of the plurality of protocols of the receiver, 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 transmitting data received from the receiver to the transmitter after the protocol specific training v is seen.
