High Speed Communication Switch on MAX II EPM240

Hi,

I am new on CPLD and FPGA development.

I have to make EtherCAT switch with two inputs and one output.Input selection would be based on "Physical button press" by user.

can anyone suggest if MAX II EPM240 would work for this use case or do i need some other variant of CPLD. (in light of High speed communication on I/O)

1. Two inputs of EtherCAT are running on 100Mbps. (Preferred 1Gbps), Input selection would be based on "User button press"

2. EtherCAT PHY would be taken care by Beckhoff Chipset.

CPLD is used only to avoid cable interchange manually.

3. Are there any limitations on I/O for these high speed signals?

ex: Speed , voltage level

so on each power cycle as per user button state - "EtherCAT Input" routed to "EtherCAT Output" automatically. to me it seems feasible with low end CPLD device also.

Regards

Nitin
