E1110 Gigabit Media Access
Controller (MAC)
OVER VIEW
The E1110 is a 10/100/1000 BaseT Ethernet media access controller
designed to support copper and fiber networks. Designed on LSI Logic’s
0.18-micron G12 process technology, the E1110 can support applications
requiring speeds ranging from 10 to 1000 Megabits per second (Mbps) on
a single platform and is an ideal solution for a variety of embedded
applications to include switches, routers, servers, and high-performance
desktop computing systems.
The E1110 is designed as a modular hard macro and can be used with or
without the legacy support for the 10/100 Megabit Ethernet. An integrated
E110 Flow Control Module allows the E1110 CoreWare to interface directly
with the E110 CoreWare for the full 10 to 1000 Mbps support. The E1110
can also be used as a stand alone MAC to support 1Gigabit Ethernet only
applications. This flexibility allows the designer to optimize the ASIC for legacy
support or minimum die size.
The Physical Interface Multiplexer offers maximum system flexibility with
interfaces for MII, GMII and TBI (fiber). The E1110 is fully MAC Layer IEEE
802.3z compliant. It also includes additional capabilities for 802.3x complaint
flow control (Symmetric/Asymmetric pause frame control), VLAN frames,
RMON, Jumbo packets, and more.
FEA T URES/BENEFITS
Advanced 0.18 micron based hard
macro reduces system cost by providing
predictable timing, lower power and
high port density integration
A programmable 10/100/1000 data
rate option that can support Jumbo
frames of up to 10,000 Bytes, highest
performance with large data transfer
Programmable Auto padding of frames
less than 64 bytes on transmit that en-
sures minimum Ethernet packet compliancy
Industry compliance for the IEEE
802.3x Flow Control and IEEE 802.3z
MAC Layer to ensure system
compatibility with legacy and future
products that are designed to industry
standards
Support for VLAN is included in the hard
macro, which simplifies its implementation
Wide variety of PHY interfaces is
supported to include MII, GMII and
TBI, which offers the most flexibility for
PHY chip selection
Statistic vector support for RMON is
included and can be used for managed
switching solutions
Indication based addresses for
Multicast, Broadcast and Unicast
packets to support standard
conventional traffic, streaming video,
movies on demand, and other
multimedia applications
