A 128Gb/s ADC/DAC Based PAM-4 Transceiver with >45dB Reach in 3nm FinFET
This work presents a low-power and high-performance long reach transceiver suitable for AI data centers and cloud computing. This ADC/DAC based transceiver is implemented in 3nm FinFET, capable of equalizing >45dB channel loss @128Gbps achieving BER < 2e-8, compatible with PCIE GEN-7 data rate. Analog power of the transceiver is as low as 1.89pJ/b, and the total power efficiency is 4.1 pJ/b.
