Agere Systems ET1011 is a gigabit Ethernet trans-
ceiver 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 µm 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 ana-
log front end that delivers robust operation, reduced
cost, and lower power consumption than traditional
Using oversampling has allowed for the implementa-
tion of a fractionally spaced equalizer, which provides
better equalization and has greater immunity to tim-
ing jitter, resulting in better signal-to-noise ratio
(SNR) and thus improved BER. In addition,
advanced timing algorithms are used to enable oper-
ation over a wider range of cabling plants.
