Abstract

In this paper, a 4-channel 1.25 to 12.5Gb/s transceiver macro with both phase and amplitude adaptive equalization is presented. It will be shown that when loss at f_s/2 exceeds 20dB, phase distortion measurably closes eyes and increases BER. The proposed transceiver cancels 4.1 to 417dB loss for 10.3Gb/s or 4.9 to 34.9dB loss for 12.5Gb/s when both phase and amplitude adaptive equalization are enabled, extending both the length and the range of channels that can be adapted compared to when only amplitude adaptive equalization is used.
