The BCM8727CIFBG from Broadcom is a dual-channel 10-GbE SFI-to-XAUI transceiver with an integrated Electronic Dispersion Compensation (EDC) equaliser, designed for high-density SFP+ line-card applications. It suits network and data-centre hardware engineers building 10-Gigabit Ethernet ports that connect to optical modules and copper twin-ax cabling.
The BCM8727 is a fully integrated SerDes device running at 10.3125 Gbps, handling the XGXS, PCS, and PMA functions that a 10-Gigabit serial Ethernet interface requires, including 8B/10B and 64B/66B coding, clock multiplication, and clock and data recovery. It is compliant with the IEEE 802.3aq 10-GbE standard and also supports 1000BASE-X for 1-GbE, and it requires an external 156.25 MHz reference clock for each port. The 324-ball BGA package and its integration benefits are described below.
Key Features of the BCM8727CIFBG
Dual-channel 10-GbE transceiver
The BCM8727CIFBG integrates two independent 10-Gigabit Ethernet channels in one device, increasing port density on line cards while reducing board area and component count.
Integrated EDC equaliser
An on-chip Electronic Dispersion Compensation equaliser corrects signal distortion across the link, supporting reliable operation over optical fibre and copper twin-ax connections.
SFI-to-XAUI conversion with full SerDes
The device performs the extension functions of a 10-Gigabit serial Ethernet interface, including 8B/10B and 64B/66B coding, clock multiplication, and clock and data recovery, all within a single SerDes.
Standards compliance
The part is fully compliant with the IEEE 802.3aq 10-GbE standard and additionally supports 1000BASE-X for 1-GbE, easing interoperability across mixed-speed networks.
324-ball BGA package
Housed in a 19 mm x 19 mm, 1 mm pitch, 324-ball BGA, the transceiver is built for surface-mount assembly on dense, high-speed line-card designs.
RoHS compliance
The BCM8727CIFBG is RoHS compliant, supporting green and compliant manufacturing for networking and data-centre hardware.
