A digital near-end crosstalk (NEXT) canceller merged with an analog equalizer for multi-lane serial-link receivers has been realized in 0.13 mu m CMOS technology. By applying the proposed sign-sign block least-mean-square (SSB-LMS) circuit, a 5 Gb/s pseudorandom binary sequence (PRBS) of 2(31)-1 suffered from both the channel loss and NEXT over 10- and 20-inch FR4 traces with the width of 5-mil and the spacing of 7-mil is successfully equalized. The measured bit error rate (BER) is 10(-12) and the measured maximum peak-to-peak jitter is 49.7 ps. This chip occupies 0.56 x 0.76 mm(2) and the whole circuit including buffers consumes 177 mW from a 1.2 V supply.
