Initially I implemented a 4 MHz clock driving 2 PIC micros, using 2 inverters, one of them as a buffer (74HC04). To avoid the waste of space (the other 4 gates do nothing) I tried a transistor oscillator and buffer from an ARRL book but couldn't have it working. In my implementation space is at a premium.
Can anyone show me a really working circuit?
BTW: input should be a 4 MHz square wave or kind of a sine wave? If so, what pk to pk value? No experience on this.
Thanks for any help.
