Marvell offers a complete portfolio of Brightlane™ Ethernet PHY transceivers, bridges and switches supporting speeds from 100Mbps to 10Gbps with enhanced safety and security features required for today’s and tomorrow’s in-vehicle networks.
Modern vehicles are becoming data centers on wheels. Advanced emerging features such as collision detection, lane departure warnings, and autonomous driving require massive amounts of secure data processing, networking and storage.
Marvell's Automotive Ethernet PHY family of solutions support 10GBASE-T1, 5GBASE-T1, 2.5GBASE-T1, 1000BASE-T1, 100BASE-T1, 1000BASE-T, 100BASE-TX, and 10BASE-T standards. 2.5G/5G/10GBASE-T1 single pair Ethernet PHY implement the Ethernet physical layer as defined by IEEE 802.3ch standard. 100/1000Base-T1 single pair Ethernet PHY implement the Ethernet physical layer as defined by the IEEE 802.3bw and IEEE 802.3bp standard. These are ideally suited for a wide range of automotive applications, they are manufactured using a standard digital CMOS process and contain all the active circuitry required to implement the physical layer functions to transmit and receive data on a single balanced twisted pair.
Automotive Ethernet PHY integrates media dependent interface (MDI) termination resistors into the PHY which simplifies the board layout and reduces board cost by reducing the number of external components. Also, they support an integrated voltage regulator to generate all required voltages so the device can run off a single 3.3V supply.
Marvell’s Automotive Ethernet Switch family of products offer advanced features designed for today’s in-vehicle networks. With advanced security, like Trusted Boot and Deep Packet Inspection, and Time Sensitive Networking features, these switches are ideal for automotive applications such as Advanced Driver Assistance Systems, Central Gateways, Body Domain Controllers, and In-Vehicle Infotainment.
The Marvell® 88QB5224 device is a multi-gigabit Ethernet bridge designed for automotive applications. The device is designed to directly connect to automotive-grade Cameras, Graphics Processing Units (GPUs), etc, via CSI-2 interface as defined by the MIPI Alliance. The bridge implements the Ethernet physical layer portion of the 10GBASE-T1 standard as defined by the IEEE 802.3ch task force.
