This paper presents a mixed signal decision feedback equalizer (DFE) efficiently implementing sign-sign least-mean-square (SS-LMS) coefficient updating, offset estimation and compensation. The equalizer is designed for multi-drop buses and has 16 six bit fully programmable filter coefficients. The equalizer filter is implemented with a novel carry-save-DAC architecture eliminating the carry propagation limiting factor. Measurement results from a test chip are presented showing no transmission errors and good clock skew robustness when receiving data at 700 Mb/s over a heavily polluted channel. The test chip also includes bit error rate (BER) measurement circuits and equalized eye-chart extraction
