Oscillators are devices that generate electrical signals whose frequency and amplitude can be continuously regulated.

347LB5I2457T

The 347LB5I2457T is a crystal-controlled oscillator. It is built with a quartz crystal which is the heart of the device. This oscillator takes advantage of the quartz crystal\'s piezoelectric property which results in an accurate frequency with very low distortion and stability. The frequency is determined by the size of the quartz resonator, and the circuit can be tuned by varying the load capacitance, as well as the frequency may also be adjusted by varying a control voltage.

Application Field

Crystal oscillators such as the 347LB5I2457T are used in a variety of applications, including radio, television, computers, lasers, and cellular telephones. The 347LB5I2457T oscillator is an ideal choice for clock applications, especially in signal conditioning and digital logic applications where accurate timekeeping and precise frequency control are required. It is also especially suitable for clocks in personal devices due to their very low power consumption and low electromagnetic interference.

Working Principle

The quartz crystal in the 347LB5I2457T is mounted between two electrodes. As the oscillator is started, an electric signal is applied to the quartz crystal, causing it to vibrate at its resonant frequency. This oscillation of the crystal produces an electrical signal with a frequency that is determined by the size and shape of the crystal. The oscillation is sustained as long as the voltage applied is within a certain range.

The frequency stability of the 347LB5I2457T is further improved with the use of feedback circuits. These circuits are used to maintain a constant frequency even when the temperature and voltage changes. Feedback is also used to reduce frequency adjustment error. Frequency adjustment can be done either dynamically or manually using a tuning knob.

The 347LB5I2457T is an important component for maintaining accurate timekeeping in many digital applications. Its low power consumption and low electromagnetic interference make it the preferred choice for portable devices.
