The MC145415P's internal architecture typically includes a voltage-controlled oscillator (VCO), a phase detector, a loop filter, and programmable dividers. The VCO generates a signal whose frequency is controlled by an input voltage. The phase detector compares the phase of the VCO output with a reference signal and generates an error signal. The loop filter smooths the error signal, which is then used to adjust the VCO's frequency. The programmable dividers allow the user to select the desired output frequency by dividing down the VCO's frequency. The lock detect output signals when the VCO is locked to the reference frequency.
