Broadcom BCM89586M Automotive BroadR-Reach® Ethernet Switch - Coming Soon
Broadcom BCM89586M Automotive BroadR-Reach® Ethernet Switch is a fully integrated BroadR-Reach multilayer switch supporting automotive qualification (AEC-Q100) for in-vehicle networking applications. The BCM89586M provides an optimal solution for high-performance and challenging low-power requirements in key automotive designs. Implementing industry-leading architecture, the BCM89586M delivers multiple intuitive low-power modes. Additionally, the device utilizes IEEE 802.1AE compliant integrated MACSEC engines that can support up to 1Gb/s of encryption and decryption on several ports and an automotive cable diagnostics feature.
The Broadcom BCM89586M Automotive BroadR-Reach Ethernet Switch interconnects with other devices for scalable, high-performance systems through multiple interfaces, including RGMII, SGMII, XFI, MII, RvMII, and PCIe. The BCM89586M switch provides IEEE 1588v2 and IEEE 802.1AS timing functions designed for both peer-to-peer and end-to-end transparent clocking-in hardware.
The BCM89586M employs a highly comprehensive automotive technology solution required by OEM and Tier-1 suppliers, meeting or exceeding CISPR 25ds component-level, ISO 11452-5 Stripline, ISO 11452-4, IEC 61000-4-2, and AEC-Q100 requirements.
The BCM89586M is housed in a 23mm x 23mm FCBGA package and is qualified up to an automotive Grade 2 temperature range (–40°C to +105°C).
