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
