We will used FPGA and to transfer ethernet data between MAC and CPU but have some question as below:
(1)whether have the IP that support for FlexE OAM,OH and IEEE 1588 function
(2)the Cyclone V GX chip (5CGXFC4C7M11I8) whether can used this IP(FlexE OAM,OH and IEEE 1588 function)
I presume you are looking for IP solution that target 5G application market ?
Unfortunately we don't have these IP solution for standard support but I do find out about special custom IP solution that may meet certain of your design requirement.
