BCM53162 Product Brief Ultra-Low Power TSN 1GbE/2.5GbE Switch with 10GbE Uplinks for Automotive 2.0 Description From the Broadcom RoboSwitch-2 BCM5316X family, the BCM53162 is a multi-gigabit 1GbE/2.5GbE switch with 10GbE uplinks that meets the requirements of the new Automotive 2.0 market. This new market encompasses the technology and business shifts associated with the transition from human-controlled to autonomous driving. As part of this shift, the In-Vehicle Network (IVN) is expected to grow in bandwidth and transition from 100MbE to multi-GbE and multi-10GbE connectivity in at least two vehicle domains: Advanced Driver Assistance System (ADAS) and backbone. Key Features Next-generation ADAS is the main vehicle domain that will enable Four 1GbE/2.5GbE SGMII+ ports autonomous driving. It includes a large set of sensors, radars, cameras, and one or more processors that analyzes the fused data inputs and decides Two 2.5GbE/10GbE XFI/SFI ports driving operations (steering, braking, speeding, and so on). The new data One 1GbE RGMII port inputs require GbE or multi-GbE connectivity, which results in 10GbE Eight 100/1000BASE-T ports connectivity to the processors. Similar to progress in ADAS networks, connecting to external the next-generation automotive backbone is based on high-bandwidth 1GbE/2.5GbE/10GbE links in ring, star, or full-mesh topologies. Figure 1 An integrated ARM Cortex-M7 CPU illustrates the architecture of a common ADAS and backbone. An RGMII, MII, and RvMII port to connect to an external CPU (or to The BCM53162 supports four 1GbE/2.5GbE SGMII ports, one 1GbE RGMII be used as a 1GbE customer port) port, two 10GE XFI/SFI ports, and an additional eight 1GbE GPHYs. The Cascading capability for creating eight GPHYs can be converted to SGMII ports by placement of external 1 a 14- to 26-port switch such as 2 PHYs . The SGMII ports on the switch (the original four and the new eight) 10GbE XFI + 8 1GE/2.5GbE SGMII enable the placement of the automotive 1000BASE-T1, BroadR-Reach technology, and PHYs. Support for Time-Sensitive Networking (TSN) feature set with Despite its high-bandwidth support, the BCM53162 can meet the power accurate clocking requirements of future electric vehicles it is extremely power efficient and Power-saving green technology consumes no more than 4.5W. Similar to other members of the BCM5316X per IEEE 802.3az Energy Efficient family, the BCM53162 integrates a powerful ARM Cortex-M7 CPU, a high- Ethernet end forwarding engine with Virtual Switching Instance (VSI) support, Support for industrial temperature an advanced Quality-of-Service (QoS) engine, a flexible Content Filter grade (40C to +85C) Processor (CFP), security features, and much more.
