The programmable oscillator can also be used in cell tower networks and air traffic control systems, as well as public safety communications and navigation systems, thanks to its high frequency stability and accuracy. It can also be used in industrial applications such as PLCs, frequency and voltage converters and medical equipment.

Working Principle

The SIT9005ACE2H-25NG Programmable Oscillator operates by converting a reference frequency to an output frequency through a divide by N/M circuit. The reference frequency is divided by an N/M prescaler, then it is further divided or multiplied by different dividers and multipliers. A digital time interval counter is used to control the frequency. The output frequency is then compared to the reference frequency and if there is a discrepancy, the output frequency is adjusted to match the reference frequency.
