HI, i Just wanted to understand this circuit better and discuss with people
So here it is a ,crystal oscillator...
It uses a 3.5Mhz Crystal... and takes feedback from emitter of the transistor ,using a Capacitive Voltage divider...
And it has 50pF Variable cap,i think it is to tune the frequency of the oscillator,am i right??
my another doubt is there are 2 capacitors 270pF and 150pF,do u think that will add up to the frequency ???
Please correct me ,if i am wrong and also explain it's working in brief for my better understanding
