Broadcom introduces second-generation automotive Ethernet switch; 30% reduction in power consumption, 50% reduction in size

Broadcom Corporation announced its next-generation BroadR-Reach automotive Ethernet switch portfolio with integrated PHYs for automotive central gateway, Advanced Driver Assistance Systems (ADAS), infotainment, head units and time-sensitive applications. The new 28 nm devices utilize a unique design that delivers 30% power savings compared to previous generation device and a 50% reduction in package size.

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 already on the road 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.

Key Features of the BCM8953x Switch include:

  • 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

The BCM8953x Switch portfolio is now sampling.
