10/100BASE-T
Transceiver
BCM5201
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.
