摘要

本文综述了10gbase - t标准在局域网环境下通过结构化铜缆进行全双工10gb /s传输的主要特点。讨论了实现10个GBASE-T收发器的权衡。然后,我们提出了在数字CMOS技术(0.13 mum)中首次实现10 GBASE-T。该收发器还支持较低的速度,以向后兼容传统以太网端口。在10 GBASE-T模式下,收发器通过四对平衡电缆运行,每对电缆由一个800 MS/s的DAC驱动,每对电缆都有一个接收器,包括一个有源回波消除电路和一个800 MS/s的ADC。10gbase - t模式下100m信道的功耗为10.5 W。收发器还包括预编码器、串扰消除器、矩阵均衡器和LDPC编码器和解码器。

(INVITED) 10GBASE-T for 10Gb/s full duplex ethernet LAN transmission over structured copper cabling
This paper reviews key features of the 10 GBASE-T standard for full duplex 10 Gb/s transmission over structured copper cabling in the LAN environment. Tradeoffs in implementing 10 GBASE-T transceivers are discussed. We then present the first implementation of 10 GBASE-T in digital CMOS technology (0.13 mum). This transceiver also supports lower speeds for backward compatibility with legacy Ethernet ports. In 10 GBASE-T mode, the transceiver operates over four pairs of balanced cabling where each pair is driven by an 800 MS/s DAC and each pair has a receiver that includes an active echo cancellation circuit and an 800 MS/sec ADC. The power consumption when operating over a 100 m channel in 10 GBASE-T mode is 10.5 W. The transceiver also includes precoders, crosstalk cancellers, matrix equalizers and an LDPC encoder and decoder.
