If the reference crystal is 12.8 M...More figuring:<br /><br />If the reference crystal is 12.8 MHz, and the reference divisor is 1024, then the PLL reference frequency is 12.5 kHz. With an 80x prescaler, that makes the basic channel step size 1 MHz. And that means that you simply set the N dip switch to the desired LO frequency in MHz.
