Tool for computing tuning to specific frequencies by use of direct ADC reading at specific timer-controlled rate to "tune" to specific frequencies either by quadrature or differential.

Crystal MHz
Target MHz

Quadrature:

I = + + - -

Q = + - - +

Differntial:

V = + - + -

You choose the mode you operate in, either Quadrature or differential

Table shows:
