How do you run a Scenix at 75Mhz? Where would you get at 75Mhz oscillator?

Hi,

We have a Scenix SX20 running at 50Mhz. We have to increase its speed to 60Mhz or 75Mhz.

Has anyone done this?

What parts could you use for this? I'm having trouble getting any parts from www.digikey.com, www.mouser.com, Farnell, or RS Components.

I'm sucessful using SX52 at 72MHZ. Sometimes I had problems when changing a signal after change other signal at same port, but NOP instruction between setb or clrb instructions solved the problem.

I'm using http://www.digikey.com/scripts/DkSearch/dksus.dll?PName?Name=300-8036-1-ND&Site=US·from epson. I found also one with 60MHZ http://www.digikey.com/scripts/DkSearch/dksus.dll?PName?Name=300-8033-1-ND&Site=US

Cristiano.

Would 66MHz also do? That's a very commonly stocked oscillator (therefore cheap...)

Hi,

Parallax offers 75 MHz clock generators (see www.parallax.com/detail.asp?product_id=252-00005) at $2.50 each.

BTW: The product description on the Parallax site names this component a "Resonator" for 75 mHz but I think it is not a resonator but a clock generator for 75 Mega Hertz, and not for 75 Milli Hertz .
