Oscillators play an important role in many signal processing and control systems as they provide the basic clock or timing signals needed for operation. The 653P156E6C3T oscillator is one such oscillator used in a wide variety of applications. In this article, we’ll explore its application fields and working principle.

The 653P156E6C3T oscillator is a crystal oscillator that uses a quartz crystal as its frequency determining part. It is a surface mount piezoelectric crystal oscillator with a wide operating temperature range of -40 to +120 degrees Celsius. It is available in package sizes from 8 pin (DIP) to 14 pin (SMD) versions. It has a frequency stabilities from 5 to 50ppm over a wide frequency range, and its operating voltage range is from 3.3 to 5 Volt. This oscillator is widely used for applications requiring high frequency stability, such as radio communication, mobile communication, vehicle equipment, handsets, watches and clocks, as well as medical and measurement equipment.

The working principle is based on the fact that a quartz crystal resonates at a particular frequency when subjected to a voltage signal. The 653P156E6C3T oscillator includes an amplifier and a frequency multiplier circuit together with a quartz crystal, to generate an oscillation with a frequency stable over a wide range of temperature and voltage variations. In an oscillator, the amplifier circuit is tuned to the resonant frequency of the quartz crystal, and the output of the amplifier circuit is fed back to the input. This results in a sustained oscillation at the resonant frequency of the crystal, with the output of the oscillator being available at the output pins.

The frequency of the oscillator can be adjusted by varying the capacitance of the load capacitance, which allows the frequency to be tuned to within the frequency range and stability of the oscillator. This makes it possible to adjust the frequency of the output signal to meet the requirements of the application. Additionally, for some applications, the oscillator output can also be divided down using a programmable counter to obtain a lower frequency output.

In conclusion, the 653P156E6C3T oscillator is a surface mount piezoelectric crystal oscillator with excellent frequency stability over a wide temperature and voltage range. It is widely used in a wide variety of applications including radio communication, mobile communication, vehicle equipment, medical and measurement equipment, watches and clocks. Its working principle is based on providing a sustained oscillation at the resonant frequency of a quartz crystal, with the frequency of the output signal being adjusted by varying the load capacitance.
