Programmable Oscillators

Programmable oscillators are a type of oscillator that can be externally programmed to produce a particular frequency or set of frequencies. The SIT9002AI-43H33DK is a programmable differential semiconductor oscillator, meaning it is a single device capable of producing two slightly different frequencies. This type of oscillator is used in applications such as electronic clock generators, frequency counters, surface acoustic wave (SAW) transceivers, and frequency synthesizers.

The SIT9002AI-43H33DK programmable oscillator is a differential semiconductor oscillator, meaning it has two differential outputs, one having a frequency slightly higher than the other. The two frequencies can range from 32 KHz to 300 MHz. The operating temperature of the oscillator can range from 0°C to 70°C, making it suitable for a variety of applications. It is also suitable for surface mount technology (SMT) assembly.

The differential outputs of the SIT9002AI-43H33DK programmable oscillator are generated by a digital control circuit and an analog output circuit. The digital control circuit consists of a voltage-controlled oscillator (VCO), a programmable frequency-select logic circuit, and a frequency-adjust logic circuit. The VCO provides a reference frequency that the digital control circuit will multiply by the desired frequency, calculated by the programmable frequency-select logic circuit and the frequency-adjust logic circuit. The calculated frequency is then transmitted to the analog output circuit, which uses an amplifier and a band-pass filter to generate an analog signal with the appropriate frequency.

The SIT9002AI-43H33DK programmable oscillator offers several unique features. It has excellent temperature stability and low phase noise, which makes it an ideal choice for applications that require accurate frequency control. It also has a high accuracy of ±10ppm, making it suitable for precision frequency control applications. It is also capable of producing a wide output range, from 0v to 5v, for greater flexibility in different environments. Finally, it has an adjustable output level, allowing the user to fine-tune the output signal.

The SIT9002AI-43H33DK programmable oscillator is an excellent choice for applications that require accurate frequency control and wide output range. Its adjustable output level makes it ideal for precision frequency control applications, such as electronic clock generators, frequency counters, SAW transceivers, and frequency synthesizers. Its high accuracy, wide temperature range, and excellent temperature stability make it a reliable and versatile device, suitable for a variety of applications.
