Working Principle

The SIT8009BIS71-18S is a programmable oscillator configured by integrated dual oscillators and a digital signal processor (DSP) block. The two oscillators are based on quartz crystals and each has independent peak-to-peak amplitude control and frequency adjustment. The DSP block is responsible for frequency tuning, amplitude adjustment, and signal conditioning.

At its totally programmable core, the signal processor adjusts the two oscillators to their optimal states. Once the signal processor has determined an optimal output frequency, the two oscillators are synchronized and then used to generate a digitally controlled, high-quality output signal. The signal processor also contains an internal EPROM that acts as a non-volatile memory, allowing custom programming of the oscillator\'s frequency and other features.
