Programmable Oscillators are special devices developed specifically for use in electronics and communications. These are used mainly for the purpose of generating signals at a specific frequency in order to send or receive data accurately. The SIT9002AC-48H25DO is one such programmable oscillator.

The SIT9002AC-48H25DO is a Voltage-to-Frequency programmable oscillator, meaning that its frequency range can be varied by varying the voltage applied to the input pins. It is capable of displaying linear frequencies from 0 to 147.45 KHz with a gain accuracy of ±7%. The device also offers an outpus with a peak current of 15mA and output voltage up to18.45Vpp.

The application fields of the SIT9002AC-48H25DO are generic frequency measurement, signal generation, frequency-shift keying (FSK) modulation and demodulation, Radio Telemetry systems and frequency control. It can be used in control system applications involving signal processing, signal conditioning, frequency/phase modulation and demodulation, as well as pulse-width modulation and demodulation.

The working principle of the SIT9002AC-48H25DO is based on the voltage-to-frequency conversion. When a positive voltage between 0 to 10V is applied to the input pin, the output frequency increases linearly with the voltage. It follows an exponential relationship when a negative voltage is applied. The output is derived from a harmonic oscillator which is synchronized with an external frequency reference. It has an input threshold voltage of 1V and an open collector output that is TTL/CMOS compatible. The device is able to self-sync to a reference frequency, and is capable of switching within 500uS for buffered sources. It also has sawtooth waveform, triangular waveform and pulse waveforms available as outputs.

The SIT9002AC-48H25DO is a very versatile piece of programmable oscillator, with a wide range of uses, including in radio telemetry, FSK modulation and demodulation, frequency control and signal processing. It has an easy to use interface and is capable of producing a variety of output waveforms, making it ideal for many applications. The device is cost-effective and reliable and can be easily integrated into a variety of systems.
