SG-8002CA 44.2368M-PCMB

SG-8002CA 44.2368M-PCMB is a one-chip oscillator applicable for various products, designed to keep up with the ultra-small frequency variation and the temperature. It is useful for a wide range of commercial and industrial applications.

The main function of SG-8002CA 44.2368M-PCMB is to provide a stable sinusoidal output signal with a required reference frequency. This oscillator uses ceramic resonator as its frequency limitation, and a loop circuit mainly composed of an oscillator transistor, buffer amplifier, and a capacitor to generate the stable output frequency. The loop circuit is capable of delivering stable performance under temperature variation and changes in the supply voltage.

The frequency of the SG-8002CA 44.2368M-PCMB oscillator is calculated by multiplying the standard frequency (f0) with a temperature coefficient. The difference between the temperature coefficients of the oscillator and the ceramic resonator results in the temperature variation of the oscillation frequency.In other words, as the temperature rise, the oscillation frequency increases.

In addition to providing stable frequency under the temperature variation, the SG-8002CA 44.2368M-PCMB oscillator also has the capability of very small frequency variation. It is mainly achieved by specifying a larger current source and also reducing the temperature coefficient of the frequency in the loop circuit. This ensures that the frequency change can be accurately monitored in the loop.

In summary, the SG-8002CA 44.2368M-PCMB oscillator is particularly suitable for products requiring stable sinusoidal output signal with reference frequency. Its features include small frequency variation and temperature stability, making it an ideal choice for both commercial and industrial applications.
