01 / DESIGNED FOR THE APPLICATION

One network.Across the vehicle.

Bring vehicle compute, networked sensors and automotive Ethernet devices together through one switch, with dedicated connections for power and pulse-per-second timing.

01

Bandwidth where it belongs

Three 10 Gbps and four 1 Gbps Ethernet interfaces use M12 X-coded connectors. Eight additional 1 Gbps automotive Ethernet interfaces use MATEnet connectors.

02

Timing at the interface

Dedicated SMA connections provide pulse-per-second (PPS) input and output for timing and synchronization within the vehicle network installation.

03

A common software foundation

Built on Microchip VelocityDRIVE, with a focus on easy configuration, high reliability and security for in-vehicle networking.

Vehicle network integration

  1. 01 / 9-36 V DC

    Power

    Supply vehicle DC power through the M12 L-coded, 5-pin connector.

  2. 02 / M12 + MATEnet

    Connect

    Connect network devices to the 10G, 1G and 1G automotive Ethernet interfaces.

  3. 03 / PPS input / output

    Align

    Use the dedicated SMA timing connections for PPS input and output.

  4. 04 / VelocityDRIVE

    Configure

    Configure the vehicle network using the IVNS software built on Microchip VelocityDRIVE.

102 Gbps describes the switch silicon capacity. The exposed port lineup totals 42 Gbps in nominal link rates per direction: (3 x 10) + (4 x 1) + (8 x 1). These values do not specify measured application throughput.

02 / CONNECTIONS THAT MATTER

Ready to integrate.

Seven M12 Ethernet interfaces and eight MATEnet automotive Ethernet interfaces, plus dedicated M12 power and SMA timing connections.
