Low latency comma detection and clock alignment |
摘要 |
An Infiniband device can be provided. The device can comprise an input port having a serialiser/deserialiser. The serialiser/deserialiser can comprise: a data buffer for storing data from a received serial data stream and for outputting the stored data in parallel groups and a code detector for detecting a predetermined code pattern in the serial data stream and generating a code detection output in response thereto. The serialiser/deserialiser can also comprise a transition detector for detecting transitions in the serial data stream and reconstructing a serial data clock therefrom, and for generating a plurality of parallel data clocks from the serial data clock, each parallel data clock having a different phase. The data buffer can be responsive to the code detection output to adjust a parallel data group start position within the serial data stream and to cause a selection of one of the reduced frequency clocks having a phase corresponding to the adjusted parallel data group start position.
