BCM53570中文资料1G/2.5G/10G/25G TSN Connectivity Switch数据手册Broadcom规格书

描述 Description

The Broadcom® StrataConnect® BCM53570 System-on-a-Chip (SoC) features an integrated high-speed ARM Cortex-A9 processor, embedded Cortex-R5 processor, and enterprise-level buffer and table sizes. It includes comprehensive IEEE standards-compliant Time-Sensitive Networking (TSN) features such as Preemption, Time Aware Scheduling, and Seamless Redundancy to provide deterministic behavior to Industrial Ethernet, 5G Wireless connectivity, and transport networks. The BCM53570 also offers unparalleled integration for supporting Ethernet time synchronization.Additional key switching features include efficiently sized tables, and MultiGigabit Ethernet (MGig) capable I/Os for 24- to 48- port SMB/SME stackable switches with uplinks.The device is well suited for high-density 1G/2.5G connectivity applications with 25G/40G/50G uplinks such as base stations, flash storage arrays, professional grade audio/visual and chassis backplanes.The BCM53570 family supports VNTag and IEEE 802.1br to implement port-extender functionality.All members of the BCM53570 family offer many shared advanced features such as IEEE 802.1Q VLAN, VLAN translation, enhanced Denial-of-Service (DoS) protection, an advanced ContentAware™ engine, IEEE VNTag and IEEE 802.1br Port Extension, and IEEE 802.1p QoS.
