Working Principle

The 375LB3I1000T oscillator utilizes the Colpitts oscillator circuit, which utilizes a combination of capacitors and inductors to generate an oscillating signal. The circuit contains two capacitors, referred to as the series capacitor and the shunt capacitor, which are connected in series with an inductor. The series capacitor and inductor form a voltage divider, while the shunt capacitor and inductor form a parallel resonant circuit. The voltage divider creates an alternating voltage which is fed into the parallel resonant circuit, where it is amplified and then fed back into the voltage divider. This feedback causes the voltage divider to oscillate, and the oscillating signal is then output from the oscillator.

The 375LB3I1000T is a voltage-controlled oscillator, which means the oscillation frequency can be controlled by varying the voltage applied to the circuit. It is capable of generating a wide range of frequencies from 500kHz to 1000kHz. In addition, the 375LB3I1000T can be used in either a single-ended or a differential configuration, making it suitable for both balanced and unbalanced systems.

Conclusion

In conclusion, the 375LB3I1000T is a highly versatile oscillator, capable of generating a wide range of frequencies in both single-ended and differential configurations. It is used in a variety of applications, including instrumentation, communications, and wireless sensing. It operates on a Colpitts oscillator circuit, and its frequency can be controlled by varying the applied voltage.
