Gigabit Ethernet For Cars


Marvell announced a new automotive Ethernet reference platform integrated with TE Connectivity’s (TE) MATEnet modular and scalable connector for automotive Ethernet. The platform enables car manufacturers to quickly prototype automotive systems with Gigabit Ethernet for advanced driver assistance systems (ADAS), electronic control units (ECU), in-vehicle infotainment (IVI) and vehicle domain gateways.

The platform supports audio video bridging (AVB) switching solutions with 100BASE-T1 and 1000BASE-T1 Ethernet physical layer (PHY) capability. The 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 A/V Bridging (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.


The 88Q2112 is said to be the industry’s first 1000BASE-T1 automotive Ethernet PHY transceiver compliant with the IEEE 802.3bp 1000BASE-T1 standard. With highest in-vehicle connectivity bandwidth, it meets the rigorous EMI requirements of an automotive system.

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. Its low power design and integrated filter reduce bill of materials (BOM) costs and enable small form factor designs. The combination of these components enables a robust infotainment and ADAS experience.

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 miniaturized standard automotive terminals, such as NanoMQS, Generation50, MCON 050 and 0.50 Series, MATEnet connectors are a global terminal platform. In addition, there is an opportunity to use TP (Twisted Pair), UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) types of cable for Ethernet applications.
