Octal-Port SGMII Copper Gigabit/IEEE1588v2 Ethernet Transceiver

Currently Viewing:

Fully integrated octal gigabit transceiver with support for Energy Efficient Ethernet™ (EEE), Synchronous Ethernet and IEEE 1588v2.
The MDI twisted-pair transceiver consists of eight triple-speed 10/100/1000BASE-T Ethernet transceivers. When in Copper mode, the PHY performs all of the physical layer functions for 10BASE-T, 100BASE-TX, 1000BASE-T, and on standard Category 5 UTP cable. The BCM54280 is designed to be compliant with the SGMII industry standards.


  • SGMII interface
  •  Support for IEEE 802.3-compliant copper line interfaces: 1000BASE-T, 100BASE-TX, 10BASE-T
  •  IEEE 802.3az Compliant (Energy Efficient Ethernet): support for native EEE MACs; support for Not Recommended for New Design non-EEE MACs using AutogrEEEn® mod
  •  SyncE, IEEE 1588v2 PTP and ITU-T Y.1731 delay measurement support
