Beijing, January 7, 2015 - Broadcom , the global leader in innovative solutions for wired and wireless communications semiconductors (NASDAQ: BRCM), recently released at the 2015 International Consumer Electronics Show in Las Vegas, USA A generation of BroadR-Reach automotive Ethernet chips optimized for low-power automotive applications. The chip is highly integrated, has excellent transmission performance, and has a transmission rate of up to 100Mbps on a single pair of unshielded twisted pairs. It has a small size (6&TImes; 6mm) and features multiple discrete devices.
Although Ethernet has been used as an IT network technology, its use in connected vehicles is growing rapidly. Broadcom's new BCM89811 physical layer transceiver (PHY) features low power consumption, enabling automotive Ethernet applications to be extended from infotainment systems and advanced driver assistance systems (ADAS) to telematics, roof shark fins, Instrument cluster, car audio host and center console module.
Broadcom's BroadR-Reach automotive Ethernet technology is currently used in multiple models and has been successfully launched. It offers many advanced features in the 2014 and 2015 BMW X5, the 2015 Jaguar Land Rover XJ and the 2015 Volkswagen Passat.
Dr. Carsten Kromke, Head of E/E-Architecture and Networking at Volkswagen, said: "With the rapid deployment of more advanced wireless connectivity, the need for higher bandwidth and scalability is increasing. Car Ethernet technology is different. The application provides the scalable bandwidth required, while also providing full control over the configuration of the in-vehicle network."
This low-power physical layer transceiver (PHY) is a new addition to Broadcom's growing portfolio of automotive Ethernet chips. Broadcom's BroadR-Reach automotive solutions not only provide the high bandwidth required for advanced security and infotainment applications, but also provide authentication and encryption to protect connected vehicles from malicious cyber attacks and threats.
Dr. Ali Abaye, Director of Automotive Business at Broadcom, said: "Car Ethernet technology has enabled the transfer of decentralized communications in a specific area into a centralized backbone architecture, giving it greater flexibility and scalability in the car. And innovative. As the backbone of the car, BroadR-Reach car Ethernet technology gives the car a luxury, plus advanced security and infotainment capabilities to meet the growing consumer experience of a true mobile connection. Demand."
Dominique Bonte, vice president and business director of ABI Research, said: "Ethernet offers a variety of mature and widely supported and deployed options to protect vehicles from malicious attacks while protecting the network infrastructure. These built-in features fully illustrate Ethernet. Technology is ready to play an important role in ensuring the safety of connected vehicles in the future."
Broadcom is a founding member of the OPEN Alliance Special Interest Group (SIG), an industry consortium dedicated to promoting the widespread adoption of Ethernet-based automotive connectivity technology as the industry standard for automotive connectivity technology. Natalie A. Wienckowski, GM's strategic leadership, core hardware team and OPEN Alliance SIG chairman, said: "The Ethernet-based connectivity technology has a huge potential in the automotive industry as a mature and broad ecosystem. OPEN Alliance The number of members has soared to nearly 250. Obviously, this shows that the automotive industry has shown great enthusiasm for it."
The BCM89811 PHY has the industry's highest level of integration, reducing the cost of expensive external components, reducing board space by more than 25%, and reducing overall bill of materials (BOM) by up to 20%1.
Key features of the BCM89811 PHY:
· Low-power process that meets automotive-grade requirements, reducing power consumption by up to 30%1
· Low-pass filter with integrated chip reduces emissions (in compliance with EMC requirements)
· Integrated internal voltage regulator provides power to the chip without the need for an external voltage regulator
· Meet high automotive specifications, eliminate noise and reduce transmission jitter
· Transmission speed on single-pair unshielded twisted pair can reach 100 Mbps, reduce wireless connection cost by up to 80%3, and cable weight is reduced by 30%4
Time to market:
Broadcom's BCM89811 PHY is currently sampling.

No matter what kind of business you own, a custom light up neon sign can vastly improve your sales by catching the attention of potential customers. The reason behind so many companies using Custom Led Light Signs are the clear benefits to displaying a Custom neon sign. Neon signs are highly visible at night or in bright sunlight, from far distances or close-by, meaning visibility and increased sales.
In addition to being used in outdoor neon signs and lighted exterior building decorating, neon lighting is a great solution for interior signs and for interior decorating effects. The bright colors of neon lighting assure your indoor signage gets noticed and neon elements in signage and décor add vibrant illumination inside your building.
