BCM5345x

Single-Chip L2/L2+ 20-24 port 2.5G/1GE + 4x10GE switch with optional integrated CPU

Currently Viewing:

System on-a-Chip (SoC) switch family offers industry-leading integration and performance in a small footprint.
 
The device offers 20-24 ports of 1GE/2.5G with 10GbE uplink ports. Offering the industry's highest level of integration, the BCM5345X family of switches has embedded serializer/deserializer (SerDes) supporting KX, KR, XFI, XAUI, RXAUI, SGMII and QSGMII modes, as well as an optional powerful 600-MHz ARM A9 single-core processor. The BCM5345X is ideal for new applications requiring a mix of 1G & 2.5G ports, such as WiFi aggregation switching for 802.11ac Wave 2, embedded designs for control/data plane applications or WebSmart switches for Small and Medium Businesses (SMB).
 
The BCM5345X device family offers multiple I/O configurations and speeds (1G/2.5G/10G) that address key segments of connectivity. With a 2MB integrated packet buffer and the industry's lowest power consumption, the BCM5345X family of switches is designed to reduce overall system costs.
 
The optimized I/O map reduces system design effort and enables low-cost printed circuit board design. The BCM5345X device family offers many advanced features, such as IEEE 802.1Q VLAN, VLAN translation, enhanced Denial of Service (DoS) protection, IPv4 and IPv6 support, an advanced ContentAware™ Engine and IEEE 802.1p Quality of Service (QoS).
