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
