A frequency-synthesiser’s VCO jumps abruptly only to pre-determined frequencies, a VCO with a variable DC control voltage smoothly glides to any frequency within its range. Other offers may also be available. What more is there to it. You can change the frequency of 74,s629 VCO because the phase detector is programmed to reduce or increase the frequency produced by the crystal. See the seller’s listing for full details.

Sellers set the item’s declared value and must comply with customs declaration laws. Then the circuit will be a single or switched frequency phase-locked-loop instead of a variable VCO. Sign In Sign Up. Please enter a number less than or equal to Instead of the additional phase-locked-loop parts, you can use a simple variable DC control voltage from a pot that I recommended to set its frequency to 10KHz.

If you use a phase detector then you will also need a stable crystal oscillator for comparison. I have seen frequency synthesizers that do the very same thing. Watch list is full.
