MAX II 300MHz clocking

Hello,

I see a lot of reference to the MAX II having:

"Support for internal clock frequency rates of up to 300 MHz".

I want to use a 300MHz source clock for my CPLD design. What is meant by "internal"? Can I provide a 300MHz clock to an input pin from outside the chip?

Thanks,

CMW

    Yes, it's possible to use clocks up to 300 MHz with MAX-II.

    Depending on the device and design, of course.

    300 MHz is working at the limits, so you should verify (static timming analysis and gate level simulation) your design before you commit to it.
