BCM5400 100/1000BASE-T GIGABIT ETHERNET TRANSCEIVER
BCM5400 FEATURES
• The Broadcom® BCM5400 is a fully integrated
100BASE-TX/1000BASE-T Gigabit Ethernet
transceiver
• IEEE 802.3u and 802.3ab compliant
• Glueless interface to an external 10BASE-T
transceiver for 10/100/1000BASE-T applications
• Digital Signal Processor (DSP) based system, including
digital adaptive equalizers, echo and crosstalk
cancellers, encoders and decoders
• ^{Link quality monitor}
• ^{Advanced power management}
• ^{Automatic detection and correction of pair swaps,}
pair skew, and pair polarity
• ^{Automatic MDI crossover}
• ^{Auto-negotiation with next page support}
• ^{On-chip transmit wave shaping eliminates external filters}
• ^{Internal 1000BASE-T hybrids simplifies external magnetics}
• ^{GMII and 10-bit interface (TBI) interfaces to the}
media access controller
• Works with any existing GB Fiber ASICs
• ^{125 MHz low jitter clock generator}
• ^{Support for jumbo packets up to 9 KB}
• ^{JTAG test interface}
• ^{3.3V/2.5V CMOS with 5V tolerant I/Os}
• ^{256-pin TBGA}
SUMMARY OF BENEFITS
• Highly robust 100/1000BASE-T transceiver designed
to operate on existing CAT 5 cable plants.
• Supports 10/100/1000BASE-T applications via
external 10BASE-T transceiver.
• Ability to dynamically sense and adapt to changes in
channel conditions of the cable plant.
• Allows early identification of network problems
through continual monitoring of link quality.
• Reduced power through intelligent power
management techniques.
• Automatically corrects common installation and
configuration mistakes with twisted-pair wiring.
• Works with any existing ASICs and MACs that
support either an industry standard 10-bit interface,
or IEEE 802.3z standard GMII interface.
• Maximizes network thoughput with support for
oversized (jumbo) packets.
• Internal 125 MHz clock generator eliminates external
clock circuit for MAC/ASIC.
• Works with low-cost transformers available from
multiple suppliers.
• ^{Flexible and programmable LED support.}
