Some embodiments operate in context of a CDR circuit of a serializer/deserializer (SERDES). For example, slope asymmetry around the first precursor of the channel pulse response for the SERDES can tend to skew at-rate CDR determinations of whether to advance or retard clocking. Accordingly, embodiments use asymmetric voting thresholds for generating each of the advance and retard signals in an attempt to de-skew the voting results and effectively tune the CDR to a position either earlier or later than the first precursor zero crossing (i.e., h(−1)=0) position. This can improve link margin and data recovery, particularly for long data channels and/or at higher data rates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"At-rate SERDES clock data recovery with controllable offset","description":"Embodiments include systems and methods for applying a controllable early/late offset to an at-rate clock data recovery (CDR) system.
