Abstract: A method and apparatus for a novel adaptive equalization technique for a Serializer/Deserializer receiver is disclosed. In one approach, adjustment of AC and DC gains is performed before DFE coefficients are adjusted. Further after the equalization an electrical idle threshold may be set based on the results of the equalization.

Abstract: Core clock alignment circuits include a serial-in parallel-out (SIPO) data processing circuit, which is configured to generate a plurality of lanes of deserialized data in response to a corresponding plurality of lanes of serialized data. The SIPO data processing circuit is further configured to generate a plurality of recovered clock signals from corresponding ones of the plurality of lanes of serialized data. These recovered clock signals may be out-of-phase relative to each other. The devices also include a plurality of lane FIFOs, which are configured to receive respective ones of the plurality of lanes of deserialized data and respective ones of the plurality of recovered clock signals at write ports thereof. A core clock alignment circuit is provided, which may be electrically coupled to the plurality of lane FIFOs.
