The BCM82328 is a low-power, low-latency PHY integrating retimer and equalizer functions supporting 40-Gigabit Ethernet (GbE) and 10GbE applications.
In 40G mode, the BCM82328 supports two full-duplex 40GbE ports (XLPPI-to-XLAUI/KR4) for SR4, LR4, and copper CR4 QSFP+ line-card applications. In 10G mode, the BCM82328 supports eight full-duplex 10GbE ports (SFI-to-XFI/KR) for SR, LR and copper CR SFP+ line-card applications. 
  The BCM82328 was designed in 28nm CMOS technology to provide a low-power and low-latency solution with integrated AC-Coupling capacitors for direct interfacing to Broadcom Trident switch products. 
  The BCM82328 is available in 17mm x 17mm, 1mm pitch, 256-pin BGA, RoHS-compliant package.
