We present a full-duplex 3 Gb/s PAM4 voltage-mode transmitter with an embedded 2-tap feed forward equalizer. In full-duplex mode, the transmitter employs an echo canceller to cancel the locally transmitted signal and recover the signal from the far-end. The transmitter achieves energy proportionality with output swings and equalizer coefficients. Fabricated in 65 nm Digital CMOS process, the transmitter transmits a maximum of 1 V peak-to-peak differential output swing. In full-duplex mode, the transmitter equalizes 2 m UTP cable and dissipates 37.3 mW at 3Gb/s with echo canceller in the receiver path. The power reduces to 18.3 mW while transmitting across a 9 m UTP cable in the half-duplex mode.

具有 2 抽头前馈均衡器的节能型 3 Gb/s PAM4 全双工发射器

我们展示了一个带有嵌入式 2 抽头前馈均衡器的全双工 3 Gb/s PAM4 电压模式发射器。在全双工模式下,发射机使用回声消除器来消除本地发射的信号并恢复来自远端的信号。发射器通过输出摆幅和均衡器系数实现能量成比例。该发射器采用 65 nm 数字 CMOS 工艺制造,可传输最大 1 V 峰峰值差分输出摆幅。在全双工模式下,发射器均衡 2 m UTP 电缆,并在接收器路径中使用回声消除器以 3Gb/s 的速率耗散 37.3 mW。在半双工模式下通过 9 m UTP 电缆传输时,功率降低至 18.3 mW。
