ET1011

Agere Systems ET1011 is a gigabit Ethernet transceiver fabricated on a single CMOS chip. Packaged in either a 128-pin TQFP or a 68-pin MLCC, the ET1011 is built on 0.13 m technology for low power consumption and application in server and desktop NIC cards. It features single power supply operation using on-chip regulator controllers. The 10/100/ 1000Base-T device is fully compliant with IEEE® 802.3, 802.3u, and 802.3ab standards.

The ET1011 uses an oversampling architecture to gather more signal energy from the communication channel than possible with traditional architectures.
The additional signal energy or analog complexity transfers into the digital domain. The result is an analog front end that delivers robust operation, reduced
cost, and lower power consumption than traditional architectures.

Using oversampling has allowed for the implementation of a fractionally spaced equalizer, which provides better equalization and has greater immunity to timing jitter, resulting in better signal-to-noise ratio (SNR) and thus improved BER. In addition, advanced timing algorithms are used to enable operation
over a wider range of cabling plants.
