The
BCM5411
is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet transceiver solution. An advanced Digital Signal
Processor based architecture, 0.18u CMOS process, and power
management techniques are used to create a design optimized for
low power operation and minimal board space.
This device represents the third generation of Gigabit Ethernet
transceivers based on the same field-proven architecture as in the
BCM5400 and BCM5401 transceivers, which demonstrate
robust operation over the installed base of CAT 5 twisted pair
wiring. The
BCM5411
is fully software and register compatible
with the BCM5400 and BCM5401.
In addition to low power operation, several modes are included
to further reduce power in special conditions. The
BCM5411
can
detect when the user disconnects the port from a network and
subsequently enters into low power modes. When energy is
detected on the line, the part re-enters normal mode of operation.
The energy detection mode is especially valuable for mobile
applications to conserve battery life when the Ethernet port is not
used.
Dissipating less than 600 mW, the
BCM5411’s
Wake-on-LAN
mode allows PC adapters and LAN-on-motherboard (LOM) to
meet stringent standby power requirements for PC’99
compliance. In the wake-on-LAN mode, the transceiver keeps
the link active at 10 Mbps or 100 Mbps while powering down all
of the internal circuitry needed for operation at Gigabit Ethernet.
Power is less than 400 mW in wake-on-LAN mode.
In addition to supporting IEEE 802.3 Standard Gigabit Media
Independent Interface (GMII), and industry standard Ten Bit
Interface (TBI),
BCM5411
also supports RGMII, a reduced pin-
count (12 versus 25) version of the GMII. In a 24-port system,
using RGMII instead of GMII results in savings of 312 pins for
MAC ASICS, thus saving systems cost significantly.
The
BCM5411
is fully compatible with the IEEE 802.3 standard
for auto-negotiation of speed. Additionally, several Plug and Play
enhancements are added to make the device even more user
friendly. A link quality indicator LED gives installers an instant
visual indication if there are any problems with the wiring plant
supporting operation at the desired speed. This includes physical
wiring defects that the
BCM5411
cannot automatically correct for
and channel conditions such as excessive cable length, return loss,
crosstalk, echo, and noise. Broadcom’s cable analyzer software
can be used with the device to provide remote management of the
cable and a first level of diagnostics and fault isolation. The
BCM5411
continually monitors various channel conditions. The
optional Ethernet@WireSpeed
TM
capability allows the
BCM5411
to auto-negotiate to the maximum data rate allowed by the cable
plant. This feature prevents failure to establish link because of
cable plant impairment at higher data rates.
