“…Any nonlinearity in (often significant) echoes cannot be canceled by the hybrid, nor by the (linear) adaptive digital filters. Cancelling the nonlinear echo components by using nonlinear adaptive filters as described in [9] is costly, mainly in terms of additional power, and is therefore not preferred.…”

The speed of Ethernet over copper cables has steadily increased by a factor of 10,000 over the last four decades, from 1Mb/s in the earliest Ethernet implementations to 10Gb/s in recent systems. This paper describes the design considerations on all levels of the 10GBASE-T design hierarchy that form the basis for the implementation of highly power-efficient AFEs in full-duplex 10GBASE-T transceivers. It also shows how these considerations are implemented in a practical design. At frequencies up to 400MHz, the transceiver presented in this paper achieves >62dBc transmitter SFDR, >62dBc echo cancellation (EC) SFDR and >60dB receiver SFDR. Achieving a bit-error-rate (BER) better than 10 −15 , it dissipates less than 1.75W at full 10Gb/s traffic over a 100m cable, which is the lowest power for a 10GBASE-T AFE published to date.
