Working Principle

SIT1602BI-21-30S-74.176000E works on the principle of LC oscillator utilizing high precision capacitors and an inductor. An external capacitor Cext is used to control the frequency of the oscillation. When a power supply is connected to the inductor-capacitor, the capacitors will charge to a voltage Vext. This voltage will create current in the inductor and an emf in the capacitor that is greater than Vin. These two effects combine to create a feedback loop so that the current oscillate to produce an undamped output. The frequency of the oscillation can be adjusted by changing the capacitance of the capacitor. As such, SIT1602BI-21-30S-74.176000E is capable of producing an output signal with a variable frequency.
