BCM5384
®
4GE PORT SWITCH WITH INTEGRATED GE COPPER PHY
FEATURES
•
Highest silicon integration level achieved for an 4-port, 10/100/1000
Ethernet switch device
SUMMARY OF BENEFITS
•
Industry-first single-chip solution for four Gigabit Ethernet.
•
Enables a new generation of lower-cost switches with Gigabit
connectivity and much smaller form factors.
•
Seventh-generation switch on a chip
•
Integrates:
Four 10/100/1000 transceivers (802.3ab compliant)
Four MACs (802.x compliant) with support for 9 Kbyte Jumbo Frames
Nonblocking four Gigabit Ethernet fully integrated switch fabric
SPI Interface for easy setup and smart unmanaged operation
•
Uses field-proven industry-standard 10/100/1000BASE-T
transceivers-lowers overall system interoperability and reliability
risks.
