Marvell has unveiled an automotive Ethernet reference platform incorporated with TE Connectivity's (TE) MATEnet modular and scalable connector intended for automotive Ethernet.

Marvell's development platform supports audio video bridging (AVB) switching solutions with 100BASE-T1 and 1000BASE-T1 Ethernet physical layer (PHY) capability. It also allows car makers to quickly prototype automotive systems with Gigabit Ethernet for electrical and electronic (E/E) architectures including in-vehicle infotainment (IVI), advanced driver assistance systems (ADAS), electronic control units (ECU) and vehicle domain gateways.

Marvell's automotive reference platform provides 100BASE-T1, 1000BASE-T1 and 10/100/1000BASE-T1 Ethernet PHY ports with advanced switching silicon. The platform includes support for the AVB networking standards of the AVnu Alliance's certification test subgroup (CDS). Support includes Stream Reservation Protocol (SRP) to provide end-to-end management of resource reservations for automotive data streams. Marvell's Ethernet PHYs enable high definition and uncompressed video, high speed links between domains to support connected and autonomous driving systems and the fastest system bring up from power down to AVB operation. Included in the reference platform are Marvell's 88Q2112 100BASE-T1 PHY and 88Q1010 100BASE-T1 PHY transceivers, 88EA6352 automotive grade AVB 7 port switch and 88EA1512 10/100/1000BASE-T PHY transceivers. The BASE-T1 technology is compatible with TE's MATEnet modular and scalable connector for automotive Ethernet. TE's offering is also compatible with Marvell's automotive reference platform and includes 1-port and 5-port links for 100/1000 BASE-T1 connectivity.

The 88Q2112 claims to be is the industry's first 1000BASE-T1 automotive Ethernet PHY transceiver compliant with the draft IEEE 802.3bp 1000BASE-T1 standard. The 88Q2112 supports the market's highest in-vehicle connectivity bandwidth and is designed to meet the rigorous EMI requirements of an automotive system, stated the company. The 1000BASE-T1 standard allows high speed and bi-directional data traffic over light weight, low cost single pair cable harnesses. The 88Q2112 enables the transport of in-vehicle uncompressed 720p30 camera video and support for multiple HD video streams, including 4K resolution. The 88Q1010 low-power PHY device supports 100BASE-T1 and is compliant with the IEEE 802.3bw 100BASE-T1 standard. The 88Q1010 supports compressed 1080p60 video for infotainment and camera systems and enables data transport in the car. Its low power design and integrated filter reduce BOM costs and enable small form factor designs.

TE's MATEnet modular and scalable connector for automotive Ethernet is designed to meet the harsh automotive environment by providing the performance needed in automotive Ethernet data transmission up to 1Gbit/s, according to IEEE 100/1000BASE-T1. Based on miniaturised standard automotive terminals, such as NanoMQS, Generation50, MCON 050 and 0.50 series, MATEnet connectors represent a global terminal platform. In addition, there is an opportunity to use twisted pair (TP), unshielded twisted pair (UTP) and shielded twisted pair (STP) types of cable for Ethernet applications. The MATEnet connector can also be adapted to customers' specific needs.
