Dual-Channel 10-Gigabit Ethernet SFI-to-XFI PHY with EDC
Dual-channel 10 GbE SFI-to-XFI (10-Gigabit serial electrical interface) PHY that incorporates an Electronic Dispersion Compensation (EDC) equalizer supporting SFP+ line-card applications.
The BCM8752 is a multirate physical layer targeted for optical fiber and copper twin-ax applications. It interfaces with both limiting- and linear-based SFP+ and SFP modules, and SFP+ copper twin-ax cable. The BCM8752 is fully compliant with the 10 GbE SFP+ standard and also supports 1000BASE-X for 1 GbE operation. The BCM8752 is developed using an all-DSP high-speed front end, providing the highest performance and most flexibility for line-card designers. An on-chip microcontroller implements the control algorithm for the DSP core.
