BCM84886B0KFEBG

The Broadcom® BCM84880 is a single-port 5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX Ethernet CMOS transceiver.The device performs all physical-layer functions for 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-TX Ethernet on Category Cat5e, 6, or 6A twisted-pair cable.The BCM84880 supports the USXGMII, XFI, 5000BASE-X, 2500BASE-X, and 1000BASE-X (SGMII) interface for connection to a MAC.The BCM84880 is a highly integrated solution combining digital adaptive equalizers, ADCs, phase-locked loops, line drivers, encoders, decoders, echo cancelers, crosstalk cancelers, and all required support circuitry.The BCM84880 features the Energy Efficient Ethernet (EEE) protocol. EEE enables the BCM84880 to auto-negotiate and operate with EEE-compliant link partners to reduce overall system power during low utilization of the link. Broadcom’s AutogrEEEn® mode permits legacy systems to enjoy the power saving benefits of EEE.The BCM84880 automatically negotiates an operating speed with any transceiver on the opposite end of the line.The BCM84880 features Enhanced Cable Diagnostics, which detects common cable problems such as shorts, opens, and cable length.
