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 new BCM8953x family creates a centralized 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.

Features:

- Second generation automotive switch with integrated BroadR-Reach PHYs enables cost-effective connectivity through lower cabling and connector costs

- Integrated low pass filters

- Advanced power savings with multiple low-power mode technologies

- Advanced architecture to support non-blocking, line-rate data transfer at wire speed performance for all frame sizes over unshielded single-pair twisted cable

- Processor subsystem able to support timing stack and Audio Video Broadcast (AVB) bridging support functions

- Enhanced design to surpass AEC-Q100 and EMC requirements
