Oscillators are regularly used in many advanced electronic or communication devices due to their ability to generate continuous, accurate, and stable signals. The SIT1602BI-81-28E-20.000000T is an example of such devices; in this article, we will discuss its application field and working principle.

Application Field

The SIT1602 features high output power, high reliability, good frequency stability, small size, and cost-effectiveness. It can be used in a variety of applications, including but not limited to:

• Communication systems
• Broadcast and navigation systems
• Home entertainment devices
• Medical instruments
• Industrial systems
• Monitoring systems

This oscillator is also suitable for use in civil aviation and military fields. It can be used for frequency-hopping spread-spectrum (FHSS) systems, asynchronous serial communication, GSM, and Bluetooth uses.

Working Principle

The SIT1602 uses a quartz crystal resonator oscillator to generate alternating current (AC) oscillations. The oscillator comprises four essential components—the crystal resonator, the amplifier, the voltage-controlled oscillator (VCO), and the frequency divider—which are connected in a chain.

When electrical energy is supplied to the crystal resonator, it will convert this energy into an AC signal. The amplifier then amplifies the AC signal before it is filtered and converted into a sine wave. The output from the amplifier is fed to the VCO, which then generates a train of rectangular voltage pulses.

The output from the VCO is filtered before it is fed to the frequency divider. The divider further reduces the frequency of the train of pulses according to the specified output frequency. The output of the divider is then fed to the output buffer, where the sine wave is amplified and presented as a stable voltage output.

The SIT1602 is reliable and accurate due to its use of a quartz crystal resonator. Its frequency output can be adjusted and maintained by an external voltage-controlled source, allowing for continuous signal output.

In summary, the SIT1602 is an oscillator that features high power output, small size, good frequency stability, and cost-effectiveness. It can be used for a range of applications, from communication systems and broadcast and navigation systems to industrial and home entertainment devices. Its working principle is based on a quartz crystal resonator, the amplifier, the VCO, and the frequency divider which are connected in series.
