Solving bandwidth issues with Broadcom's high-performance BroadR-Reach Ethernet technology

As demand and expectations for various advanced technologies in the automotive sector, such as ADAS and infotainment, rise, the security of networks capable of integrating these technologies remains a critical challenge. In response, Broadcom has unveiled a portfolio of next-generation BroadR- ^Reach® automotive Ethernet switches with PHY integration for applications requiring precise time control.

The new 28-nanometer device is an automotive switch solution that uses a unique design to reduce power consumption by 30% compared to previous products, making it the industry's lowest-power solution. The rapid increase in in-vehicle applications is placing a strain on vehicle networks, thereby increasing the demand for bandwidth. Through Broadcom's high-performance BroadR-Reach Ethernet technology, automotive manufacturers can not only solve bandwidth issues but also implement secure networks while complying with the latest standards.

The wired Ethernet connection acts as a vehicle network gateway and provides device authentication to protect the car from malicious attacks, eavesdropping, and unauthorized device installations. In addition, Broadcom’s new product family, the BCM8953x, enhances the consumer experience by creating a centralized switch that combines previously independent connections, such as rear cameras, instrumentation, and audio and video streaming, enabling data sharing between various applications.

Broadcom's BroadR-Reach automotive Ethernet technology is currently installed in a variety of vehicles, including the BMW X3, X4, X5, X6, i3, i8, 6, and 7 Series, Jaguar XJ and XF, and Volkswagen Passat.

Over 500 million Ethernet ports will be installed in cars by 2030.

Ali Abaye, Senior Director of Broadcom’s Automotive Business Unit, stated, “The performance, scalability, and reliability of Ethernet technology demonstrate the infinite potential of the automotive market, as evidenced by expert predictions that over 500 million Ethernet ports will be installed in vehicles by 2030.” He added, “With the launch of our next-generation high-density BroadR-Reach device, Broadcom has reduced power consumption by up to 30% and lowered BOM costs, which will contribute to successful deployment and adoption.”

“Automotive Ethernet originated in Europe, but the newly launched next-generation Ethernet switch, with its small size and low-power design, will contribute to unlocking immense possibilities and greater opportunities anywhere, especially across Asia, including Japan,” said Ian Riches, Director and Strategic Analyst at Global Automotive Practice. “Based on standard technology, Broadcom’s BroadR-Reach technology provides a secure foundation for accelerating connected car development on a global scale.”
