Broadcom announced what it claims is the world’s first Ethernet-based connectivity portfolio engineered specifically to meet the qualifications and demands of the automotive semiconductor market. Broadcom’s BroadR-Reach® technology provides high-performance bandwidth of 100Mbps and beyond while reducing connectivity costs up to 80% and cabling weight as much as 30%.
Next-generation connected car As the prevalence of in-vehicle electronics continues to grow in volume and complexity, automotive manufacturers are under constant pressure to deliver competitive, innovative features while minimizing cost. Broadcom’s BroadR-Reach automotive solutions allow multiple in-vehicle systems (such as infotainment, automated driver assistance, and on board-diagnostics) to simultaneously access information over unshielded single twisted pair cable. By eliminating heavier shielded cabling, automotive manufacturers can significantly reduce connectivity costs and cabling weight.
The Broadcom BroadR-Reach automotive portfolio consists of five devices including three highly integrated switches with embedded PHYs, and two stand-alone PHY solutions. Each device in the automotive portfolio is designed to meet in-car EMC requirements, extreme automotive temperature grades, and TS16949 compliancy. AEC-Q100 qualification is currently under way.

Another benefit that I found that might be present other than the reduced connectivity costs is the ability to use less material. By eliminating heavier shielded cabling, automotive manufacturers can significantly reduce the amount of material used, effectively making the car slightly more environmentally friendly. Perhaps that will be another factor that will lead to the wide spread use of this connected car ethernet portfolio.
