Clocking an FPGA??

Can anyone recommend a suitable clocking circuitry, crystal or clock
component for clocking an fpga at 100MHz. Thanks

If all you need is a fixed frequency, crystal oscillators that run at 100MHz
are standard components.

Besides a straight Quartz Oscillator, available with
HCMOS output, the newer parts have internal PLLs that
allow you to feed them with 20 to 50MHz or so.

Otherwise there are PLL chips such as the Cypress CY27EE16
plus many more.
Micrel also comes to my mind.

Hi.

You can use a DALLAS IC "DS1075-100"

There is already an FPGA board that use it and it works at 100Mhz. Take a
look at http://www.xess.com/
