A 4-channel 10.3Gb/s transceiver with adaptive phase equalizer for 4-to-41dB loss PCB channel

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...

Zusammenfassung:	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.
