Working Principle

The SG5032CCN 3.276800M-HJGA3 oscillator is a monolithic voltage controlled oscillator (VCO) that uses a voltage-controlled capacitor bank to provide a range of output frequencies ranging from 3.276800MHz to 10MHz. The oscillator is based on a simple oscillator topology, with the circuit consisting of a voltage-controlled oscillator (VCO) and an active filter. The VCO is formed by an NPN transistor that generates an output signal that is frequency-dependent on the voltage applied to the capacitor bank. In the frequency-determining circuit, the capacitor bank consists of five capacitors, which are voltage-controlled by the ontrack voltage control pin. The capacitor bank is connected to the oscillator’s closed-loop feedback system, which ensures that the VCO is locked to the desired frequency.

The oscillator’s active filter is formed by two op-amps and a resistor-capacitor network, which are used to filter out the signal’s unwanted components. The op-amps are also used to tune the frequency of the oscillator, allowing the user to select the desired frequency range to meet their application’s requirements. The active filter helps to reduce the ripple and harmonics that are present in the signal, allowing the oscillator to produce a clean and stable output signal.

SG5032CCN 3.276800M-HJGA3 also features a wide range of control inputs, including frequency selection, temperature compensation, voltage control, and external clock selection. These inputs allow the user to select the desired output frequency range to meet their application’s requirements. The oscillator also features a temperature compensation circuit, which is used to maintain the oscillator’s stability under changing temperatures. Finally, the oscillator features two control pins for external clock selection, allowing the user to synchronize the oscillator to an external source.

In conclusion, the SG5032CCN 3.276800M-HJGA3 oscillator is a reliable and cost-effective solution for a variety of frequency-dependent applications. It is suitable for use in applications where high precision and stability are required, such as cellular communication systems, PCM transmission systems, measurement equipment, environmental monitoring, and industrial machinery. The oscillator’s wide range of control inputs, low phase noise, and high stability make it an ideal choice for a variety of applications.
