Marvell's Brightlane™ third generation secure Automotive Ethernet switch, 88Q5152, is a 9-port switch with integrated 1000BASE-T1, 100BASE-T1, and 10BASE-T1S PHYs fully compliant to the applicable IEEE 802.3 standards.
The 9-port switch offers 6 integrated PHYs, 2x supporting dual speed 1000/100BASE-T1, 3x supporting dual speed 100/10BASE-T1(S), and 1x supporting 100BASE-T1/TX. Additional interfaces supported include 2x Multi-speed 10Gb SerDes (10G/5G/2.5G/1Gbps), 1x multi-speed 2.5Gb Serdes (2.5G/1Gbps), 2x RGMII/MII/RMII, and 1x PCIe Gen3 x1 interface.
The port interface options offer flexible configurations for connectivity to external devices, such as 2.5/5/10GBASE-T1 PHYs, or uplinks to host SoCs. This makes the device ideal for In Vehicle Networking (IVN) applications, such as Advanced Driver Assist Systems (ADAS), Zonal Control Modules, and Central Gateways.
This switch includes a high-performance dual core ARM® R52 CPU that operates in lockstep, with dedicated on-chip memory to support Time Sensitive Networking (TSN) protocols such as Precision Time Protocol (PTP) and security firewall to protect from external malicious attacks.
The switch includes many advanced security features, including 802.1AE MACsec to provide link security to prevent man-in-the-middle attacks, Denial of Service (DoS) engine, TCAM for deep packet inspection (DPI), and trusted boot functionality to secure the vehicle network. It also includes an embedded Hardware Security Module to enhance device security by supporting secure and encrypted boot and managing advanced security features such as MACsec.
