BCM5334x数据手册Broadcom中文资料规格书

描述 Description

The BCM53344 and BCM53346 System-on-a-Chip (SoC) switch family offers industry-leading integration and performance in a small footprint. The device offers up to 24 multilayer Gigabit Ethernet (GbE) ports and a maximum of four integrated 1G and 10G SerDes transceivers, respectively, in a small package. Offering the industry's highest level of integration, the BCM53344 and 53346 have embedded 16 GbE (Physical Layers) PHYs and a powerful 400 MHz ARM® Cortex™-A9 processor. The BCM53344 and BCM53346 are ideal for cost-sensitive edge connectivity applications, such as WebSmart switches for small to medium businesses (SMB). The BCM53344 and 53346 device family offers I/O configurations that address key segments of edge connectivity. To reduce the overall system cost, the device is engineered for low-power operation to enable up to 48x GbE + 4x 10GbE (or 13G stacking) designs. Furthermore, the device I/O is optimized for simplified board layout. When used with the Broadcom QSGMII PHY, both the BCM53344 and 53346 devices can be connected to the PHYs without any trace crossovers.
