Bcm89885
Broadcom BCM89885 is a highly specialized, automotive-grade Ethernet Physical Layer (PHY) transceiver
Elias checked the schematics. The BCM89885 relied on a 25MHz crystal oscillator for its timing. Without that rhythm, the entire logic gate collapsed. He probed the clock pin with his oscilloscope. bcm89885
- 1000 Mbps (Gigabit) – Full-duplex over a single pair.
- Backward Compatibility: Supports 100BASE-T1 (100 Mbps) and 10BASE-T1S (10 Mbps) for mixed-speed networks.
- Standards: Compliant with IEEE 802.3bp (1000BASE-T1) and automotive OEM specific requirements.
