Abstract
A receiver is provided that includes a plurality of sub-rate receiver lanes each of which is configured to receive an analog receive signal from an analog front-end and produce digital sub-rate receiver data. The receiver includes one or more first digital-to-analog converters (DACs) (also referred to herein as 'average' DACs) shared across the plurality of sub-rate receiver lanes, and one or more second DACs (also referred to herein as “mismatch cancellation” DACs) for each sub-rate receiver lane of the plurality of sub-rate receiver lanes. The one or more second DACs of a respective sub-rate receiver lane provide output to be combined with an output of a corresponding one of the one or more first DACs during processing of the analog receive signal in the respective sub-rate receiver lane to account for a sub-rate receiver lane specific offset with respect to a corresponding one of the one or more first DACs.
