Let’s talk In-Vehicle Network Switch
A 15-port in-vehicle network switch combining 10 Gigabit, Gigabit and automotive Ethernet, with PPS timing connections and Microchip VelocityDRIVE software.
Preliminary specifications · Rev 0.1
Bring vehicle compute, networked sensors and automotive Ethernet devices together through one switch, with dedicated connections for power and pulse-per-second timing.
Three 10 Gbps and four 1 Gbps Ethernet interfaces use M12 X-coded connectors. Eight additional 1 Gbps automotive Ethernet interfaces use MATEnet connectors.
Dedicated SMA connections provide pulse-per-second (PPS) input and output for timing and synchronization within the vehicle network installation.
Built on Microchip VelocityDRIVE, with a focus on easy configuration, high reliability and security for in-vehicle networking.
Supply vehicle DC power through the M12 L-coded, 5-pin connector.
Connect network devices to the 10G, 1G and 1G automotive Ethernet interfaces.
Use the dedicated SMA timing connections for PPS input and output.
Configure the vehicle network using the IVNS software built on Microchip VelocityDRIVE.
