UNH-IOL Lab Expands Interoperability Testing and Support for 40G/100G, Including Automotive Ethernet
The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based networking testing and standards conformance services, announced expanded interoperability testing and support for 40 and 100 Gigabit Ethernet (40G/100G) including automotive Ethernet, 25Gb/s serial-lanes, Power over Ethernet (PoE), and Backplane. This activity is taking place within several of the UNH-IOL’s consortia and collaborative testing programs.
With heightened demand for 40G products in 2014, the UNH-IOL 40 and 100 Gigabit Ethernet Consortium has seen a significant increase in participation from members seeking 40G interoperability which, along with IEEE standards-compliance, is a helpful market differentiator.
First 100G Products Received
NXP Semiconductors N.V. and TTTech have signed a Memorandum of Understanding to jointly develop automotive Ethernet switch solutions supporting OPEN Alliance BroadR-Reach® Ethernet PHY technology. The switch chip will be specifically designed for the automotive market, but will also be suitable for various demanding industrial real-time applications.
NXP has been working with industry partners to establish BroadR-Reach as an open, de facto standard for in-vehicle Ethernet. Under the agreement, TTTech will provide the switch IP while NXP implements the IP into Ethernet switch solutions with integrated PHY.

Single-pair Ethernet is currently being deployed in automobiles over unshielded twisted pair (UTP) cable. Ethernet shows great promise as an in-vehicle networking technology for the connected car due to its ubiquity, tools, modularity, and IP support.
Although some infotainment display and camera-based advanced driver assistance system (ADAS) applications have introduced Ethernet to prove the technology, serializer/deserializer (SerDes) architectures (sometimes incorrectly called LVDS) typically are simpler, offer higher video quality, and are less expensive in these systems.
Let’s compare these two technologies in detail using a four-camera surround view application as an example.
Ethernet automotive solution delivers 100Mbps over unshielded single twisted pair cable
Broadcom Corporation announced the world’s broadest automotive Ethernet portfolio, engineered to meet the rigorous qualifications and demands of the automotive semiconductor market. Broadcom’s BroadR-Reach® automotive portfolio delivers high-performance bandwidth of 100Mbps and beyond while dramatically reducing connectivity costs up to 80 percent(1) and cabling weight as much as 30 percent(2).
The Broadcom automotive Ethernet product portfolio consists of five devices including three highly integrated switches with embedded PHYs, and two stand-alone PHY solutions. Each device in the automotive portfolio is designed to meet in-car EMC requirements and extreme automotive temperature grades. Broadcom is TS16949 compliant and AEC-Q100 qualification is currently under way.
NXP products based on Broadcom’s BroadR-Reach planned for 2012
NXP Semiconductors N.V. announced its engagement in automotive Ethernet as the first automotive semiconductor supplier to license Broadcom’s BroadR-Reach® Ethernet technology for in-vehicle networking.
NXP said it plans to create an automotive-grade product portfolio for the Ethernet physical layer based upon BroadR-Reach®, leveraging NXP’s expertise in automotive electronics and in the industry’s quality requirements, as well as NXP’s application expertise. The first NXP product samples are expected to be available in the second half of 2012.
