DECISION FEEDBACK EQUALIZER ('DFE') WITH A PLURALITY OF INDEPENDENTLY-CONTROLLED ISOLATED POWER DOMAINS

摘要

A Decision Feedback Equalizer (DFE) that includes: a plurality of input signal lines comprising at least one data signal line and a plurality of power control signal lines; at least one output signal line; and a plurality of independently-controlled isolated power domains, where each independently-controlled isolated power domain is coupled to a corresponding one of the power control signal lines, each of the power control signal lines configured to transmit a power control signal to the independently-controlled isolated power domain dynamically, and each independently-controlled isolated power domain selectively consumes power in response to the power control signal, each independently-controlled isolated power domain configured to be dynamically powered up or powered down without impacting signal processing operations.
