A 32 Gb/s Simultaneous Bidirectional Source-Synchronous Transceiver with Adaptive Echo Cancellation in 28nm CMOS Conference Paper uri icon


  • 2019 IEEE. A simultaneous bidirectional (SBD) transceiver employs an efficient voltage-mode driver with a resistor-transconductance (R-gm) hybrid to enable transmission and reception of data on a single differential channel at the same time. An FIR filter-based adaptive echo cancellation system that cancels both near-end and far-end echoes allows for the support of a wide range of channels, while a continuous-time linear equalizer efficiently compensates for channel loss. The quarter-rate source-synchronous transceiver utilizes a 5/4X phase interpolator-based clock and data recovery system to set the optimum data sampling point. Fabricated in 28nm CMOS, the 32Gb/s SBD transceiver achieves 1.83mW/Gb/s and compensates for up to 10.2dB loss.
