transceiver
• Supports 10/100/1000BASE-T applications via
• IEEE 802.3u and 802.3ab compliant
• Glueless interface to an external 10BASE-T
transceiver for 10/100/1000BASE-T applications
Signal Processor (DSP) based system,
• Digital adaptive equalizers, echo and crosstalkincluding
digital
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
B E N E F I T S
• Highly robust 100/1000BASE-T transceiver designed
is a fully integrated
• The Broadcom® BCM5400 Gigabit Ethernet
100BASE-TX/1000BASE-T
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.
