摘要
A single analog filter structure within a partial response channel combines an antialias low pass filter and a time domain waveform shaping equalizer upstream of a digital sampler. The filter also improves latencies associated with timing acquisition of a sampler clock generator loop by removing the latency of a separate equalization filter. The filter also provides a method for adapting a combination of internal filter state voltages and currents in real time for optimizing pole locations of the analog filter structure, during both data and timing recovery operations of the channel.
