5W
• ^{676-pin PBGA package}
• ^{The BCM5348M includes:}
- Twenty-four 10/100 transceivers for TX/FX
- Forty-eight media access controllers
- Five Gigabit media access controllers
- Four megabit total of packet buffer and control memory
- Nonblocking switch fabric supports up to 48 FE + 4 GbE ports
• ^{Flexible TCAM-based ContentAware™ Classification technology}
for affordable security and Access Control List
• ^{Double Tagging enables ISP applications.}
• ^{Enables a new generation of lower cost FE switches with the}
highest integration of enhanced L2+ features and maximum
connectivity.
• ^{Optimized for WebSuperSmart™ managed switch design.}
• ^{802.1Q VLAN allows segmentation of network into smaller}
broadcast domains to preserve bandwidth and increase network
security.
• ^{Four flexible Class of Service (CoS) queues per port ensure the}
lowest latency to high-priority traffic. This enables the switch to
support a wide variety of delay-sensitive video and audio multicast
applications.
• ^{IEEE 802.3ad link aggregation increases effective bandwidth and}
provides redundancy of a link.
• ^{IEEE 802.1X Extensive Authentication Protocol over LAN}
(EAPOL) plus MAC address locking enhances network port
security.
• ^{Storm and Bandwidth/Rate Control provide better traffic profile}
management.
• ^{Access to all internal registers through EB Bus, SPI, or MDC/}
MDIO interfaces.
• ^{Hardware support for implementing SNMP and RMON.}
• ^{Low-power consumption and embedded regulators allow simple}
PCB design.
