Overview

BCM89811 is Broadcom’s next-generation BroadR-Reach automotive Ethernet chip, optimized

for use in low-power automotive applications.

Delivering 100 megabit-per-second (Mb/s) performance over a single, unshielded twisted-pair wire,

the highly integrated chip combines the functionality of multiple discrete devices in an ultra-small

package (6x6 mm).

Features

Automotive-qualified low-power design reduces power

consumption up to 30 percent

On-chip integrated low-pass filters lower emissions (meets

EMC requirements)

Integrated internal regulators provide on-chip power and

eliminate the need for external regulators

Exceeds automotive specifications for noise cancellation

and transmission jitter

Delivers 100 Mb/s over single, unshielded twisted-pair

wiring, delivering up to an 80 percent reduction in

connectivity cost and 30 percent reduction in cabling weight
