GTX Transceivers for 10GBase-KX ethernet

Jump to solution

Good afternoon,

 

I am designing a circuit card that uses the xc7z045 SoC.  From my research, I notice that Xilinx provides the PCS/PMA IP to communicate via 10GBase-KR Ethernet. 

 

Can I also use the transceivers to communicate via 10GBase-KX Ethernet?  Or will I need a separate PHY chip?  Does Xilinx provide IP for this standard of Ethernet?

 

Thank you for your time.

The 10 Gigabit Ethernet PCS/PMA (10GBASE-R) is a no charge Xilinx LogiCORE which provides a XGMII interface  to a 10 Gigabit Ethernet MAC and implements a 10.3125 Gbps serial single channel PHY providing a direct connection to a XFP using the XFI electrical specification or SFP+ optical module using SFI electrical specification. This optical module can be connect to a 10GBASE-SR, -LR or –ER optical link.. Separate phy not needed 

Thanks and Regards

Thank you, Balkrishan,

 

I had one more follow-up question.  Does the IP also support 10GBase-KX4 (8b/10b encoding), or only 10GBase-KR (64b/66b encoding)?  I am trying to communicate over a VPX backplane using 10GBase-KX4.

 

Thanks again for your time and expertise,

-Kent

The intent of my original question was to discern Xilinx's support of KX4 Ethernet, as opposed to KR Ethernet.  Any technical knowledge on the subject is still appreciated.

 

Thank you,
