Dual-channel 10-Gigabit Ethernet (GbE) SFI-to-XAUI™ LAN/WAN PHY that incorporates an electronic dispersion compensation (EDC) equalizer supporting SFP+ line card applications.
The BCM84728 is a lower-power version of the BCM8728 dual SFI-to-XAUI PHY and also supports 1588 and WAN interface Sublayer (WIS) mode. The BCM84728 is a multirate physical layer device targeted for SMF, multimode fiber (MMF) or copper twin-ax applications interfacing to both limiting-based and linear-based SFP+ and SFP modules. The BCM84728 is fully compliant with the 10GbE IEEE 802.3aq standard and also supports 1000BASE-X and SGMII modes.


  • Dual-channel SFI-to-XAUI transceiver
  • Supports SFP+ SR, LR and LRM optical interfaces
  • SFF-8431 CX1 compliant
  • LRM mode supports 300m of MMF, exceeding the IEEE 802.3aq standard
