1. A reference generator circuit for a receiver module coupled to a digital communications channel, the reference generator circuit comprising:
- a reference level generation module that generates an adjustable reference level within the receiver module;
an error measurement module, coupled to the reference level generation module, to determine an error statistic based upon a comparison between a received signal and a desired signal, wherein the error statistic is collected using a sign of a recovered datum and a sign of an error; and
wherein the reference level generation module uses the error statistic to control the magnitude of the adjustable reference level.
