Hi PF,
I am trying out LM565 PLL IC and designed the basic circuit for checking free running frequency f0 (2.5 KHz). I verified the f0 by not giving any input signal (input pin floating, should I GND it ??)
Now the problem is that while sweeping the frequencies up and down the free running frequency doesn't come inside the capture range.
What to do now?
