I'm using a xtal for my project, as I need an accurate timebase, and I have to be cheap (production device). So no can oscillator. I'm wanting a stable 1MHtz source to drive the ISD chip as well, one locked to the CPU clock. The obvious thing to do is to tap into the xtal output. So, can somebody tell me what sort of electronic wizardry I have to do to make the 4MHtz crystal drive some sort of gate so I can divide by 4 and drive the ISD chip??? -- Anniepoo Need loco motors? http://www.idiom.com/~anniepoo/depot/motors.html
