Introduction
Agere Systems ET1011 is a gigabit Ethernet trans-
ceiver fabricated on a single CMOS chip. Packaged
in either a 128-pin TQFP, an 84-pin MLCC, or a
68-pin MLCC, the ET1011 is built on 0.13 µm tech-
nology for low power consumption and application in
server and desktop NIC cards. It features single
power supply operation using on-chip regulator con-
trollers. The 10/100/1000Base-T device is fully com-
pliant 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
architectures.
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.

Gigabit Ethernet Transceiver
Functional Description
Agere Systems ET1011 is a gigabit Ethernet transceiver that simultaneously transmits and receives on each of the
four UTP pairs of category 5 cable (signal dimensions or channels A, B, C, and D) at 125 Msymbols/s using five-
level pulse amplitude modulation (PAM). Figure 1 is a block diagram of its basic configuration.

Oversampling Architecture
The ET1011 architecture uses oversampling tech-
niques to sample at two times the symbol rate. A frac-
tionally spaced feed forward equalizer (FFE) adapts to
remove intersymbol interference (ISI) and to shape the
spectrum of the received signal to maximize the (SNR)
at the trellis decoder input. The FFE equalizes the
channel to a fixed target response. Oversampling
enables the use of a fractionally spaced equalizer
(FSE) structure for the FFE, resulting in symbol rate
clocking for both the FFE and the rest of the receiver.
This provides robust operation and substantial power
savings.
Automatic Speed Downshift
Automatic speed downshift is an enhanced feature of
autonegotiation that allows the ET1011 to:
Fallback in speed, based on cabling conditions or
link partner abilities.
Operate over CAT-3 cabling (in 10Base-T mode).
Operate over two-pair CAT-5 cabling (in 100Base-TX
mode).
For speed fallback, the ET1011 first tries to autonegoti-
ate by advertising 1000Base-T capability. After a num-
ber of failed attempts to bring up the link, the ET1011
falls back to advertising 100Base-TX and restarts the
autonegotiation process. This process continues
through all speeds down to 10Base-T. At this point,
there are no lower speeds to try and so the host
enables all technologies and starts again.
PHY configuration register, address 22, bits 11and 10
enable automatic speed downshift and specifies if fall-
back to 10Base-T is allowed. PHY control register,
address 23, bits 11and 12 specify the number of failed
attempts before downshift (programmable to 1, 2, 3, or
4 attempts).
