Abstract
The present invention relates in general to a method, apparatus, and article of manufacture for providing high-speed digital communications through a communications channel. In one aspect, the present invention employs an automatic slicer level adaption to enhance the performance of a high speed communications system.
Claims11
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.
