BCM5401
BCM5401
Provides robust operation at 1000 Mbps on existing CAT 5
cable plants.
Supports 10/100/1000BASE-T applications.
Dynamically senses and adapts to changes in the channel
conditions of the cable plant.
Backward software compatibility with, and similar layout to,
the BCM5400 allows easy migration to the newest technology.
Does not require heat sink or airflow.
Allows characterization of cable plant and immediate
indication of cabling issues for 1000BASE-T.
Simplifies installation and diagnostics of cable plants.
Automatically configures the link to support the highest
possible speed (10/100/1000 Mbps and full-duplex or half-
duplex operation).
125-MHz clock eliminates costly external clocking circuitry for
the MAC/ASIC.
Compatible with any existing MAC/ASIC that supports either
an industry-standard 10-bit interface (TBI) or IEEE 802.3z
standard GMII.
Flexible and programmable LED support.
• Includes visual link quality indicator
