ABSTRACT:
Channel equalization in a 1000BASE-T receiver is performed by a fixed mode analog filter2suitable for the longest possible cable length, by a FFE (3), and by a digital filter4. The digital filter (4) has two sets of taps. One set is optimal for shorter cable lengths and so cancels adaptation for long cable lengths and assists operation of the analog filter. A decision block (5) selects an appropriate set of taps.
