Broadcom Pursues Automotive Ethernet

Broadcom introduced a set of automotive Ethernet solutions aimed at connecting multiple in-vehicle systems, such as infotainment, on-board diagnostics and automated driver assistance over unshielded single twisted pair cable.


Broadcom's BroadR-Reach automotive portfolio aims to reduce in-vehicle connectivity complexity, cost and cabling weight using familiar Ethernet. The company is introducing the first five devices in this portfolio, including three highly integrated switches with embedded PHYs, and two stand-alone PHY solutions. The devices meet in-car EMC requirements and extreme automotive temperature grades.

The new chips:


BCM89500

  • 7-port, layer 2 switch with four integrated BroadR-Reach PHYs

  • Designed to support IEEE 1588 and IEEE 802.1AS timing functions

  • Deep sleep and ultra-low power modes for reduced power consumption
BCM89501
  • 7-port, layer 2 switch with five integrated BroadR-Reach PHYs

  • Designed to support IEEE 1588 and IEEE 802.1AS timing functions

  • Deep sleep and ultra-low power modes for reduced power consumption
BCM89200

  • 4-port, layer 2 switch with two integrated BroadR-Reach PHYs

  • Supports various uplink ports for connectivity to external devices

  • Designed to support IEEE 1588 and IEEE 802.1AS timing functions

  • Deep sleep and ultra-low power modes for reduced power consumption
BCM89610
  • Single-port, 10/100/1000BASE-T PHY

  • Optimized for in-vehicle diagnostic applications for when vehicle is powered off

  • Supports variety of connectivity options for external devices
BCM89810
  • Single-port, 100Mbps BroadR-Reach PHY

  • Optimized for multiple in-car network applications for when vehicle is powered on

  • Supports variety of connectivity options for external devices

  • In November, Broadcom, NXP, Freescale, and Harman announced the formation of the OPEN Alliance Special Interest Group, whose mission is to drive wide scale adoption of Ethernet-based automotive connectivity. Jointly developed with founding automotive members BMW and Hyundai Motor Company, the OPEN Alliance (One-Pair Ether-Net) SIG will address industry requirements for improving in-vehicle safety, comfort, and infotainment, while significantly reducing network complexity and cabling costs.
