Dual-Channel 10-GbE SFI-to-XAUI™ LAN/WAN PHY with 1588

The Broadcom BCM84728 is a 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 (PHY) 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.
