The Broadcom® BCM89820 is a 100 Mb/s automotive
Ethernet transceiver integrated into a single
monolithic CMOS chip. The device performs all the
physical layer (PHY) functions for BroadR-Reach®-
encoded Ethernet packets over single-pair
unshielded twisted-pair copper wire, such as FlexRay.
The BCM89820 is designed to exceed automotive
specifications for noise cancellation and transmission
jitter, providing consistent and reliable operation over
the broadest range of existing single-pair twisted-pair
automotive cable plants
