656L64453I3T Application Field and Working Principle

The 656L64453I3T oscillator is widely used in legacy systems for volume adjustment, temperature monitoring, and communication over long distances. It can also be used in digital signal processing and audio systems. It was developed by National Semiconductor and released commercially in 1982. The oscillator is based on a negative feedback design which helps maintain a stable output frequency.

Application Field

The 656L64453I3T oscillator has been used in many areas where precision and stability are required. The oscillator has been used in a variety of applications such as controlling digital signal processing, temperature measurement, data communications, and even wireless communication. It has also been used for low-precision frequency measurements and for clock generation.

In particular, the oscillator is used in radio and television broadcasting, military communications, medical equipment, and other areas that require a stable frequency signal. It is often used to provide a reference frequency for audio components. It is also used in aerospace and automotive applications, as well as for controlling high-efficiency motors.

Working Principle

The 656L64453I3T oscillator works by providing a negative feedback signal which is fed back into the system. The negative feedback signal helps maintain a stable output frequency. When the frequency of the output signal deviates from the desired set point, the negative feedback signal helps to restore the signal to the desired frequency. This helps to ensure that the output is stable at all times.

The oscillator also contains a voltage-controlled oscillator circuit which helps to provide the desired frequency. This circuit contains an active element such as a transistor or a diode which is used to generate a frequency-controlled voltage. This voltage is then used to control the output frequency of the oscillator.

The 656L64453I3T oscillator is typically constructed using two integrated circuits. The first is a low-power oscillator which is used to generate the desired frequency. The second is a voltage-controlled crystal oscillator (VCXO) which is used to provide the negative feedback signal for maintaining the desired frequency.

The 656L64453I3T oscillator is a reliable, low-cost, and stable frequency source which has been used in many areas since its release in 1982. Due to its popularity, it is still used in a variety of applications today and is likely to remain in use for many years to come.
