Overview
The 28-port
E
T4000 is part of the Agere
Systems
E
T4K family of gigabit
E
thernet
switch chip sets. These cost-effective, true
switch-on-chip solutions have been
developed to help simplify your design and
production efforts for Gb
E
switching systems.
The Agere Systems
E
T4000 is a complete
switch solution that provides 28 gigabit
E
thernet (Gb
E
) ports (I
EEE
compliant 802.3z
10/100/1000 Mbits/s
E
thernet MACs) in a
single chip. Twenty-four of the MACs connect
to external PHYs via 6-pin LVDS SGMII
interfaces, four can be connected to external
fiber PHYs via SerDes interfaces.
The
E
T4000 is offered in a 525-pin FCBGA
package and is fabricated in advanced
0.13 m CMOS process technology. The
complete solution is designed to address
the power and size constraints in switching
applications. A seamless interface and
common API for use with the Agere
E
T1081
TruePHYTM multiport PHY will help reduce
costs and ensure performance.
The
E
T4000 is a highly integrated and fully featured
Layer 2 Ethernet bridge with integrated MACs, packet
buffers, and address tables. Its high levels of integration
can help significantly reduce design costs, reduce power
and space requirements, and increase reliability. The
E
T4000 offers proven TCP/IP network security features
such as L2/L3/L4 ACL as well as QoS capabilities. It
offers advanced service recognition and queuing to
support the ability to create and manage new QoS-
based services. These comprehensive QoS features and
the
E
T4000 wire speed performance enables enterprise
desktop aggregation switching applications.
A reference system design kit is available for the
E
T4000,
for more information please contact your Agere Systems
sales representative.

Applications
The Agere Systems
E
T4000 chip set solutions are used to create competitive Layer 2+ gigabit
E
thernet desktop switches. They
can be used for a 24-port port gigabit
E
thernet switch in standalone configuration, or with the addition of four fiber ports in
standalone configuration, or in high-density gigabit
E
thernet fabric switches.
