The internal oscillator core produces an output frequency which is tuned by the external voltage-controlled signal. Its working principle details that the oscillator works thanks to the combination of the voltage controlled oscillator, the gate and the mixer. The mixer receives the output adjust voltage from the output frequency here and submits the output frequency to the voltage controlled oscillator thanks to the oscillator’s control pin. The mixer and the gate act as buffers between the oscillator and the output frequency. The oscillator then varies its frequency depending on the voltage fed to it, ranging from 2.2V to 3.6V. A step size granularity of 8KHz is achieved by the superb frequency tuning capability of the TC-29.4912MCD-T. In short, the oscillator processes a given input voltage to produce a generated frequency (output signal) and can vary in frequency depending on the input voltage.
