Abstract:
1. An integrated circuit to receive a series of symbols over a communication channel, the integrated circuit comprising: a continuous-time equalizer to reduce intersymbol interference from a most-recently received symbol in the series; a decision-feedback equalizer to reduce intersymbol interference from symbols other than the most-recently received symbol in the series; a data sampler to produce data samples from an equalized signal generated by the continuous-time equalizer and the decision-feedback equalizer; and an adaptation engine to separately adjust a a low-frequency gain and a high-frequency gain provided by the continuous-time equalizer in dependence on the most-recently received symbol in the series, the adaptation engine to adjust an amount of equalization provided by the decision-feedback equalizer in dependence on the symbols other than the most-recently received symbol in the series and independent of the most-recently received symbol in the series.
