Oscillators

An oscillator is an electronic device that produces an alternating electric current or voltage of a certain frequency. The most common type of oscillator is the SIT1602BC-73-33N-33.000000D. This oscillator is a PLL (phase-locked loop) voltage-controlled crystal oscillator with a high-stability frequency.

Application Field

The SIT1602BC-73-33N-33.000000D is often used in a wide variety of applications such as frequency synthesis, telecoms equipment, automotive and electrical systems, and instrumentation. It is also used in frequency-hopping applications, high-frequency switching, clock synchronisation, and communication equipment.

The frequency stability and phase accuracy of the SIT1602BC-73-33N-33.000000D is particularly suitable for applications such as frequency synthesizers, oscillators for telecoms equipment, and other systems that require accurate and reliable frequency control. In addition, the SIT1602BC-73-33N-33.000000D is capable of supporting power supply variations from +5V to +12V.

Working Principle

The working principle of the SIT1602BC-73-33N-33.000000D is based on the phase-locked loop (PLL) technique. PLLs are a type of feedback control system that uses two or more signals in a closed loop to control the phase or frequency of an output signal. The phase of the output signal is locked to that of the input signal, and the frequency of the output signal is a multiple of the input signal.

The SIT1602BC-73-33N-33.000000D uses a voltage-controlled crystal oscillator (VCXO) as the main component. A VCXO contains a quartz crystal and a small capacitor which resonates at a specific frequency. The frequency of the crystal is determined by the amount of voltage applied to it, allowing the frequency to be adjusted by varying the voltage. The frequency of the VCXO is then locked to the reference source using the PLL technique.

The SIT1602BC-73-33N-33.000000D also uses a pair of differential sampled analog multipliers (DSAM) to improve the frequency stability and eliminate phase jitter. The DSAM provides a high loop gain which helps to maintain the accurate frequency control. The voltage-controlled crystal oscillator and the differential sampled analog multipliers are then combined with a low-noise amplifier which amplifies the output amplitude of the oscillator.

Conclusion

The SIT1602BC-73-33N-33.000000D oscillator is a PLL voltage-controlled crystal oscillator with high frequency stability and phase accuracy. It can be used in a wide variety of applications, including frequency synthesis, communication equipment, automotive and electrical systems, instrumentation, and frequency-hopping applications. The working principle of the SIT1602BC-73-33N-33.000000D is based on the PLL technique, in which a voltage-controlled crystal oscillator and differential sampled analog multipliers are combined with a low-noise amplifier to adjust and lock the output frequency.
