Broadcom has announced its next-gen BroadR-Reach automotive Ethernet switch portfolio with integrated PHYs for automotive central gateway, ADAS, infotainment, head units and time-sensitive applications. The 28nm devices utilise a unique design that delivers 30% power savings to provide the industry's lowest power automotive switch solution.

The dramatic rise of in-car applications has led to an increase in demand for bandwidth, creating strain on the car's network. Through the use of Broadcom's high-performance BroadR-Reach Ethernet technology, automotive manufacturers not only address bandwidth concerns but also ensure compliance with the latest standards and enable a secure network. Serving as the car's network gateway, wired Ethernet connectivity provides device authentication to protect the car from malicious attacks, eavesdropping and the installation of non-approved devices. Additionally, Broadcom's BCM8953x family creates a centralised switch that brings together previously standalone connections such as back-up camera, instrumentation, audio and video streaming to share data across various applications and improve the user experience.

Broadcom's BroadR-Reach automotive Ethernet technology is on the road today in a wide range of vehicles, including: the BMW X3, X4, X5, X6, i3, i8, 6 series and 7 series vehicles; the Jaguar XJ and XF; and the Volkswagen Passat.

Dr. Ali Abaye, Senior Director, Automotive, Broadcom, commented: "The performance, scalability and security of Ethernet technology demonstrates massive potential for the automotive market, with experts predicting up to 0.5bn Ethernet ports to be deployed in cars by 2020. With our next-gen highly integrated BroadR-Reach devices, Broadcom reduces power consumption by 30% and cuts down BOM costs, paving the road for successful mainstream adoption."

The BCM8953x switch portfolio is now sampling.
