Oscillators: 653L15626A2T Application Field and Working Principle

Oscillators are one of the important components in electronic engineering and are widely used in many fields. The 653L15626A2T oscillator is especially a popular product due to its advantages.

The 653L15626A2T oscillator is a low power, low jitter, low EMI, and high reliability chip oscillating device. Its highly reliable design features include power-frequency compensation, frequency-retention, positive-slope compensation, and automated calibration.

Application Field

The 653L15626A2T oscillator is suitable for many application fields. It can be used for frequency generation in portable communication/network equipment such as mobile phones, tablets, and PCs. Its low jitter and low electromagnetic interference characteristics make it especially suitable for high-speed signal processing and communication. It can also be used to generate high-precision reference signals for general-purpose equipment, such as in industrial control, automotive, and healthcare applications.

Working Principle

The 653L15626A2T oscillator consists of a temperature compensated crystal oscillator (TCXO) and an acceleration sensor. Its working principle is that when the acceleration sensor detects an acceleration, it will generate a signal which will be used by the TCXO to adjust the output frequency. The acceleration signal is filtered and then amplified by the acceleration amplifier to the level where it can drive the TCXO. The TCXO then adjusts its output frequency by changing its capacitance.

The 653L15626A2T oscillator also features adjustment reference voltage (Vref). When the acceleration sensor is accelerating, it will output a corresponding signal to the voltage reference circuit. This voltage will then be used by the reference voltage to adjust the output frequency, so as to compensate the variation caused by acceleration.

Conclusion

The 653L15626A2T oscillator is a low power, low jitter, low EMI, and high reliability chip oscillating device, which is suitable for many application fields. Its working principle mainly lies in the temperature compensation crystal oscillator combined with the acceleration sensor, and the adjustment reference voltage.
