Programmable oscillators are electronic components that generate multiple types of frequencies. By adjusting certain parameters or adjusting the voltage or current input, these oscillators can be programmed to generate the desired frequency output. SIT9002AI-18N25DO is a programmable oscillator, which integrates two basic features: tunable frequency range and wide frequency selection. It is a precision, high-reliability, programmable crystal oscillator module whose operation is controlled by the temperature coefficient (TC) of quartz crystals used.

SIT9002AI-18N25DO programmable oscillator is widely used in many fields, such as cellular and wireless communication, automotive electronics, audio/video equipment, robotics, medical systems, IoT and industrial automation.

The SIT9002AI-18N25DO programmable oscillator has various applications in radio frequency (RF) equipment. It can be used as an oscillator for radio frequency transmitters and receivers, as well as for the generation of local oscillator and reference frequencies for bandwidth control and other analog signal processing applications. This programmable oscillator can also be used as a timing clock in digital signal processing (DSP) hardware. In addition, the SIT9002AI-18N25DO programmable oscillator can also be used as a reference clock in microwave/millimeter wave frequency range applications.

The working principle of the SIT9002AI-18N25DO programmable oscillator is based on the temperature coefficient (TC) of the quartz crystals used. This programmable oscillator uses a system where two quartz crystals, one of which may be tuned, are connected to a voltage-controlled oscillator (VCO). The output frequency of the VCO is then compared with a reference oscillator, and the difference is fed back to the quartz crystal tuning circuit. This feedback process tunes the oscillator to stabilize the output frequency and is continually adjusted depending on environmental conditions.

The SIT9002AI-18N25DO programmable oscillator is capable of generating frequencies from 10MHz to 75MHz. It also provides a temperature range of -25°C to 85°C and a maximum package size of 18 x 4.5 mm. It has a very low EMI radiation level of -50dBm @ fc< 2GHz. With its features, the SIT9002AI-18N25DO programmable oscillator provides excellent accuracy and reliability, making it ideal for a wide range of applications.

In summary, the SIT9002AI-18N25DO programmable oscillator is a precision, high-reliability, programmable crystal oscillator module that is widely used in cellular and wireless communication, automotive electronics, audio/video equipment, robotics, medical systems, IoT, industrial automation, and radio frequency and microwave/millimeter wave frequency applications. Its working principle is based on the temperature coefficient (TC) of quartz crystals used.
