I am trying to generate oscillation to calculate rise time,fall time using circuit given. What change I have done is replaced inveter with SN74LS14. But I am not getting output .Crystal used is FX135A-327 .Any idea why its not working .
Should I change Load capacitance from 22pf to 12.5 pf.Is IC SN74LS14 correct for this testing.
