Broadcom BCM54811 10/100/1000BASE-T Transceivers
Broadcom BCM54811 BroadR-Reach Single-Port 10/100/1000BASE-T Transceiver is a triple-speed Gigabit Ethernet (GbE) transceiver. The BCM54811 integrates into a single monolithic CMOS chip and performs all physical layer (PHY) 1000BASE-T, 100BASE-TX, and 10BASE-T functions on 5 UTP. The 10BASE-T Ethernet can run on standard categories 3, 4, and 5 UTP.The BCM54811 exceeds IEEE specifications for noise cancellation and transmission jitter. Consistent and reliable operation is achieved over the broadest range of existing cable plants.
