SIT1602BI-12-33S-24.000000E Application Field and Working Principle

SIT1602BI-12-33S-24.000000E oscillators, commonly referred to as a Synthesizer Integrated Technology (SIT) oscillator, are a type of stabilized oscillator, which provide excellent short-term stability over a wide temperature range.

These oscillators are ideal for applications in telecommunications, automotive, industrial, and computer systems, where jitter, temperature stability, and accuracy are prime criteria for performance. SIT oscillators are commonly used in various communication systems such as LTE (4G), WiMAX (5G), Ethernet, WiFi, and UWB, along with many other applications such as navigation systems. The most common form factor for these oscillators is a 4-pin SOT23-N package.

The working principle of a SIT oscillator is based on a modified Pierce oscillator topology. It is a quartz crystal oscillator that uses a resonator-capacitor (resonator-capacitor) circuit to provide reliable frequency stabilization in the presence of environment variables such as temperature, vibration, and drive current.

The resonator-capacitor circuit consists of a quartz crystal resonator connected in parallel with a small capacitance. This capacitance is part of a feedback loop, which in turn produces an output frequency that is proportional to the loop gain of the overall system.

The resonator is connected in series with a buffer amplifier, which further reduces the overall loop gain, resulting in a better short-term frequency stability. The frequency of oscillation can be changed by adjusting the bias current of the amplifier and the capacitance of the resonator-capacitor circuit.

In addition, the oscillator stage contains a small amount of temperature compensation circuitry, which further reduces the effect of environmental variation on the output frequency. This ensures that the oscillator maintains its specifications over a wide temperature range.

Overall, the SIT1602BI-12-33S-24.000000E oscillator provides an excellent level of noise rejection, frequency stability, and temperature compensation, making it an ideal device for precision timing applications.
