<p>A data receiver equalization technique utilizes a receiver clock (110) that has a frequency different from the incoming data frequency (i.e., an "asynchronous clock") to asynchronously sample the incoming data waveform. The resulting information about the data, typically including the rise and/or fall times, overshoot and/or undershoot, and amplitude, may be used to equalize (106) a data channel. Other adjustments to the receiver, including the gain level (105) and DC offset compensation (104), may also be made using the resulting information. An illustrative embodiment using clocked comparators, continuous-time comparators, and a statistical analysis circuit is shown. <IMAGE></p> |
