Bcm89885

Even at <1W, the BCM89885 can get warm in a sealed ECU under the hood (125°C ambient). Use thermal vias to a ground plane and populate the exposed pad (EPAD) fully.

Use case: Automotive Gigabit Ethernet (1000BASE-T1) / ADAS / Zonal architecture bcm89885

The BCM89885 is a crucial component in modern networking, providing the physical layer foundation for reliable and high-speed Ethernet connectivity. Its applications span from enterprise networking gear to consumer electronics, highlighting its versatility and the importance of PHY chips in today's connected world. Even at &lt;1W, the BCM89885 can get warm

One of the biggest pain points in automotive Ethernet has been power management. The BCM89888 fully supports (Sleep/Wake specification for 1000BASE-T1). This allows the PHY to enter a near-zero-power sleep state (typically < 20 µA) and wake up via a dedicated wake pulse (WUP) or via normal link activity. For electric vehicles, where every milliwatt impacts range, this feature is critical. Its applications span from enterprise networking gear to

, it shares the following characteristics with its product family: Standards Compliance : Supports 100BASE-T1 (100 Mbps) and 1000BASE-T1
