The BCM89885 performs all physical-layer functions to transmit Ethernet packets over a single pair of shielded (STP) or unshielded (UTP) twisted-pair cables. Supports 100 Mbps and 1 Gbps (1000BASE-T1).
The device requires a 25 MHz crystal or external oscillator. For jitter-sensitive applications (e.g., video streaming), use a low-jitter TCXO rather than a standard crystal.
The engine bay and cabin of a vehicle are plagued by electromagnetic interference (EMI) from alternators, electric motors, and wireless signals. Broadcom embeds digital adaptive equalizers, echo cancelers, and crosstalk cancelers directly onto the chip. This digital signal processing (DSP) power ensures flawless data delivery while meeting stringent automotive EMC restrictions. 3. Low Latency for Time-Sensitive Systems
