Working Principle

The SIT9005ACL1H-28EA works by scanning a specified frequency range for the precise frequency desired by the user. Upon finding the precise frequency, the oscillator then generates a signal at that particular frequency.The oscillator utilizes a multi-stage oscillator design with two independent stages. The first stage is used to determine the precise frequency that the user requests, while the second is a frequency synthesizer used to produce the precise output frequency. This two-stage approach ensures a precise and reliable output frequency.The output of the oscillator is fixed at either a sine or square wave depending on the model chosen by the user. It is also possible to program the oscillator to produce different duty cycles for the output waveform, for example a 50% duty cycle for a sine wave or a 95% duty cycle for a square wave.
