Abstract :
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.
