Oscillations--intertrack capacitance - Electronic Circuits Projects Diagrams Free

Electrix · 20th September 2005, 03:52 PM

I am building a circuit that requires a PIC micro running with 2 XTAL Oscillators. (The main clock and one for the Timer 1) Now I'm using the PIC16F73 which has pins 9-10 for main oscillr and pins 11-12 for Timer1 oscillator..I initailly thought of making the circuit on a Gerenal Purpose Board (Punch through Holes Type). But I fear that the oscillations from adjacent XTALs could play havoc !!
How should I go about designing my PCB ?? I have almost always used my General Purpose Board for small circuits..but for this one I need your opinion...

Try it and see!, I don't see it being a problem, your fears are mostly groundless.
