Stratix IV GX dev kit

--- Quote Start ---

I am looking at buying the Stratix IV dev kit. It comes with 8 transceivers routed to SMA connectors, but I need 16. Is it feasible to (with a decent performance) synchronize two of this boards by using the clock input/output?

Any other thoughts on what to use to get this 16 transmitters working?

You mean the Stratix IV SI kit?

You can also use the Stratix IV GX development kit. It has two HSMC connectors with 8 + 6 transceivers, and then the PCIe edge connector with another 8 transceivers. Samtec sells cables for HSMC-to-SMA breakout and for PCIe-to-SMA breakout.

The DE4 kit could also be used.

Cheers,
