Working principle of 520L15DT16M3690

VCO (Voltage Controlled Oscillator) oscillators are circuits that are designed to produce an output signal with a frequency which is proportional to the applied input voltage. The 520L15DT16M3690 is such a type of VCO oscillator that works on the principle of avalanche transistor population inversion.

It consists of a transistor array electrically connected between two voltage sources. A voltage is applied to the gate (G) of each transistor of the array, which then triggers population inversion. As a result, current flows between the two voltage sources and generates an oscillatory signal that can subsequently be amplified or wave-shaped by a suitable amplifying circuit.

The 520L15DT16M3690 has two modes of operation; free running mode and frequency locked mode. In the free running mode, the signal can have a wide range of frequencies, whereas in the frequency locked mode, the signal frequency is locked to a specific frequency determined by a digital control logic.

The 520L15DT16M3690 also has a built-in temperature compensation circuit to eliminate any effect of ambient temperature on the oscillation frequency. This helps maintain the output frequency accuracy to an acceptable level of 0.3%.

Conclusion

520L15DT16M3690 is a VCO (Voltage Controlled Oscillator) oscillator, which is used for a variety of applications including, radio transmission and reception, industrial motors, synthesiser circuits, and healthcare devices. It works on the principle of avalanche transistor population inversion, and has two modes of operation; free running mode and frequency locked mode. It also has a built-in temperature compensation circuit to maintain the output frequency accuracy.
