January 15, 2015 – Broadcom, a global wired and wireless semiconductor company, today announced the next-generation BroadR-Reach® automotive Ethernet chip optimized for low-power automotive applications. The newly announced high-density chip provides 100 Mbps performance over a single UTP wire and integrates the functions of various devices into an ultra-small package (6 x 6 mm). Broadcom also showcased this product at CES 2015 (International Consumer Electronics Show), held in Las Vegas, USA, from January 6 to 9.

While Ethernet has long been used as an IT network technology, its application in connected cars is also increasing rapidly. The low-power capabilities of Broadcom’s newly released BCM89811 PHY will enable new use cases extending beyond infotainment and ADAS to telematics, shark fin antennas, instrument clusters, head units, and center stack module applications. Broadcom’s BroadR-Reach automotive Ethernet technology is already on the market and is enabling diverse functionalities across a wide range of vehicle models, including the 2014 and 2015 BMW X5, 2015 Jaguar Land Rover XJ, and 2015 Volkswagen Passat.

"As the introduction of more sophisticated connectivity features increases rapidly, so too does the demand for high bandwidth and scalability," said Dr. Carsten Kromke, Head of the E/E Architecture and Network Group at Volkswagen AG. "Automotive Ethernet provides control over the entire in-vehicle network configuration while offering the scalable bandwidth required for various applications."

The newly announced low-power PHY is the latest addition to Broadcom's growing automotive Ethernet chip portfolio. Broadcom's BroadR-Reach automotive solution provides advanced security features, the high bandwidth required for infotainment applications, and authentication and encryption capabilities to protect connected cars from malicious cyber attacks and threats.

Furthermore, Ali Abaye, Senior Director of Product Marketing at Broadcom, stated, “Automotive Ethernet is accelerating the shift from distributed domain-specific communications to centralized backbone architectures to provide greater flexibility, scalability, and innovation within the vehicle.” He added, “BroadR-Reach automotive Ethernet devices serve as the network backbone for automobiles. They meet customer demands for connected experiences on the move and are enabling the widespread adoption of advanced safety and infotainment features beyond the luxury class.”

Broadcom is a founding member of the OPEN (One-Pair Ether-Net) Alliance SIG, an industry consortium launched to promote the widespread adoption of Ethernet-based automotive connectivity and establish it as a standard networking technology. Natalie A., Chair of the OPEN Alliance SIG and Strategy Leader of the Core Hardware Team at General Motors (GM) "Ethernet-based connectivity in automobiles is a proven technology with a vast ecosystem and holds infinite possibilities," Wienckowski said, adding, "The fact that the number of members in the OPEN Alliance SIG has surged to 250 in a short period of time clearly shows the passion of companies for the automotive industry."

The BCM89811 PHY provides industry-leading integration, reduces board space by more than 25% by eliminating costly external components, and reduces overall BOM costs by up to 20%.

Key functions of BCM89811 PHY

 Low-power design suitable for automobiles reduces power consumption by up to 30%

 Reduced electromagnetic emissions through low-pass filter integration (meets EMC requirements)

 Eliminates the need for an external regulator by providing on-chip power through internal regulator integration.

 Meets automotive specifications for noise cancellation and transmission jitter

 Provides 100Mbps speed with a single UTP wire, realizing up to 80% reduction in wiring costs and 30% reduction in cable weight.

BCM89811 PHY is currently SamIt is possible to provide a play.
