Oscillators

Oscillators are devices or circuitry that are primarily responsible for generating an alternating current or voltage signal. They are components that are frequently used in a variety of electronic applications, including telecommunications, audio, navigation, and even biomedical instruments. They are also used in controlling the frequency of clocks, watches, and other timekeeping or measuring devices.

Among oscillators, SIT1602BI-21-30N-12.000000E oscillator is a type of Voltage Controlled Oscillators (VCOs). It is a low-noise oscillator with an operating voltage range of 0.85V to 1.8V and a frequency range of 12MHz to 30MHz. It features a high level of linearity, with a maximum output swing of up to ±500 mV. It also has a low start-up current of 7mA.

Application Field and Working Principle

SIT1602BI-21-30N-12.000000E oscillator is most suitable for applications in high-frequency signal transmission, signal modulation and demodulation, which includes radio communication, navigation, and television. Additionally, this oscillator can be used for fixed-frequency radio transmitter system to provide an output frequency range of 12MHz to 30MHz.

In terms of working principle, it is mainly driven by a voltage-controlled element, which controls the frequency of output by adjusting the output voltage level. The VCO runs in an astable multivibrator configuration, generating a periodic train of pulses. The main components of the multivibrator circuit include a pair of transistors and two capacitors, C1 and C2. When the trigger voltage is applied to the circuit, pulses of one particular frequency are produced. The frequency of these pulses is dependent on the values of capacitors C1 and C2. The output of the multivibrator is then fed into an amplifier for further conditioning.

The SIT1602BI-21-30N-12.000000E oscillator also integrates an internal phase frequency detector (PFD) to obtain a precise frequency with minimal jitter. This PFD helps to ensure that the frequency of the oscillator remains stable, regardless of variations in the operating voltage or temperature. In addition, it incorporates a logic-controlled signal charge pump to generate the voltage needed for the oscillator to start operating upon power-on.

Therefore, thanks to its features such as low start-up current, high output swing, and stable frequency characteristics, the SIT1602BI-21-30N-12.000000E oscillator is suitable for numerous applications in the fields of telecommunications, navigation, and radio communication.
