BCM54220B0KFBG

BCM54220B0KFBG is a fully integrated dual-copper Gigabit Ethernet transceiver with support for energy efficient ethernet (EEE), synchronous ethernet (SyncE), and IEEE 1588v2 standards. The PHY performs all of the physical layer functions for 10BASE-T, 100BASE-TX 1000BASE-T, on standard Category 5e UTP cable. The BCM54220 supports both the SGMII and RGMII industry standards. It is based on the proven digital-signal processor technology of Broadcom, combining digital adaptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders, echo cancelers, crosstalk cancelers, and all other required support circuitry integrated into a single, monolithic CMOS chip. Designed for reliable operation over worst-case Category 5e cable plants, the BCM54220 automatically negotiates with any transceiver on the opposite end of the wire to agree on an operating speed. Applications include carrier, enterprise, small and medium business (SMB), industrial automation, smart grid markets.
