BCM5340数据手册集成电路（IC）的控制器规格书PDF

描述 Description

System on-a-Chip (SoC) switch family offers industry-leading integration and performance in a small footprint. The device offers up to 16 multilayer 10GbE ports. Offering the industry's highest level of integration, the BCM5340X/BCM5341X family of switches has embedded 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 BCM5340X/BCM5341X is ideal for cost-sensitive connectivity applications such as embedded designs for control/data plane applications, or WebSmart switches for Small and Medium Businesses (SMB). The BCM5340X/BCM5341X device family offers multiple I/O configurations and speeds (1G/2.5G/5G/10G) that address key segments of connectivity. With a 2MB integrated packet buffer and the industry's lowest power consumption at 500 mW per 10G port, the BCM5340X/BCM5341X 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 BCM5340X/BCM5341X 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).
