描述 Description

The Broadcom® BCM84886 is a dual-port 10GBASE-T/5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX Ethernet CMOS transceiver. BCM848886 is a highly integrated solution that supports USXGMII, XFI, 5000BASE-X, 2500BASE-X, and 1000BASE-X (SGMII) MAC interface The BCM848886 features the Energy Efficient Ethernet (EEE) protocol. EEE enables the BCM84886 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 BCM84886 features Enhanced Cable Diagnostics, which detects common cable problems such as shorts, opens, and cable length.
