BCM5317 FEATURES
8-Port Stand-Alone Unmanaged 10/100 Switch
•
Enables a new generation of lower cost 10/100
switches in much smaller form factors.
•
Utilizes field-proven industry-standard
10BASE-T/100BASE-TX Fast Ethernet
Transceivers–lowering overall system
interoperability and reliability risks.
•
Flexible interfaces support a wider variety of
application needs–fiber for long distances or an
additional 100TX port.
•
Sufficient address range handles all remote office,
branch office and home office needs.
•
Flexible architecture enables high engineering leverage
when designing multiple platforms.
•
CPUs are not required to initialize and run in cost-
sensitive unmanaged applications–providing true
Plug and Play connectivity.
•
Very low power and small footprint enables more cost-
effective system options.
•
Ability to gather and support basic management
statistics using a very low-cost microcontroller.
•
Low-cost management using the on-chip MIB registers
allows the collection and transmission of statistics for
each port and allows an upward migration path for
corporate users.
•
On-chip HP auto-MDI/MDIX feature automatically
detects and corrects for crossover cables and allows
direct switch-to-switch connection.
