SIT1602BI-21-33S-25.000000E (hereafter SIT1602BI) is a standard oscillator device belonging to the family of oscillators. Oscillators are electronic circuits that repeatedly and periodically generate a specific waveform voltage at a fundamental frequency. They play a crucial role in a wide range of electronic circuits, providing the necessary clock signal for digital logic circuits, and are also employed in radio and television transmitters as well as in many other applications where periodic timing signals are required.

SIT1602BI is a crystal oscillator with a frequency stability of ± 25 ppm at temperature fluctuations from -20°C to +70°C. The device features a frequency range from 16.000 MHz to 33.000 MHz and provides three types of output (Clipped-Sine, CMOS, Sine) with a maximum surge rating of ± 500 mV. Furthermore, SIT1602BI has a robust construction which allows it to withstand extreme conditions such as a shock rating of 300g and vibration of 16 grams.

SIT1602BI can be applied in a variety of applications such as wireless communication systems, computer systems, modems and power supplies. Due to its high frequency stability and excellent performance, SIT1602BI is an ideal choice for a range of critical-timing applications, including cellular phones, GSM systems, imaging systems, telemetry systems, space systems, and military and aerospace applications.

In terms of working principle, SIT1602BI operates using the quartz crystal method. The crystal oscillator circuit consists of two main parts. The first part is the oscillator resonator, which consists of a Quartz crystal and two capacitors. The second part is the oscillator amplifier, which works by amplifying the electrical signals that are generated by the resonator into a useable voltage. The amplifier can be configured to provide either a sine wave, clipped sine wave, or a CMOS output, depending on the type of application.

The amplified signal is integrated with an external resistor and capacitor to form an RC oscillator circuit. The crystal and the capacitors together make up a band pass oscillator, where the output signal is tuned to the crystal’s resonant frequency. The output waveform generated by the RC oscillator is then fed into the amplifier to form the desired output signal. This amplified signal is then fed as the output of the oscillator.

The main advantages of a SIT1602BI crystal oscillator are low power consumption, excellent frequency stability, high reliability, rugged shock and vibration performance, and a wide frequency range. As a result, it is an excellent choice for demanding timing applications in receivers, modulators, and other systems where precise timing control is required.
