Programmable Oscillators have become an integral part of many electronic devices thanks to their versatility and ability to create a wide spectrum of specific frequency ranges, and an even wider array of potential applications. SIT3809AC-C-25NY is an example of one application-specific programmable oscillator that is designed for particular applications in specific environments. This article will briefly explore the application field of the SIT3809AC-C-25NY and discuss its working principle.

The SIT3809AC-C-25NY is a programmable oscillator specifically designed for applications in very low noise and high temperature environments such as in mobile communication. This oscillator is constructed with a patented quartz resonator and a 10/15/25 MHz center frequency capability. It is also rated at a very low total harmonic distortion of less than 0.1%, making it suitable for use in cellular base stations, satellite receivers, space environments, and robotic systems. Additionally, the oscillator features programmable output level control and operating temperature range capability of -40°C to +85°C with a 15 years life cycle guarantee.

The working principle of the SIT3809AC-C-25NY is based on a quartz-based resonator. Quartz resonators are dropped off from a high frequency and then frequency locked by applying an external signal. This frequency locked signal is then divided into different parts and then passed through programmable filters to attain the desired desired frequency. The frequency locked signal can be further tuned to acquire the perfect frequency balance. This type of frequency lock oscillator makes it possible for the SIT3809AC-C-25NY to maintain frequency accuracy within +/-50 ppm over temperature ranges at operating temperatures.

The SIT3809AC-C-25NY is also packaged in hermetic, lead-free QFN-16 packages, which are RoHS compatible and are also used in automotive applications. The device is also compliant to the IEC615-1 standard, and it is able to operate in a wide range of frequency bands making it suitable for communication systems that require precise oscillations in order to achieve signal stability and long-term accuracy.

In summary, the SIT3809AC-C-25NY is an application-specific programmable oscillator designed for use in very low noise and high temperature environments. It has a 10/15/25 MHz center frequency capability and is rated for a very low total harmonic distortion of less than 0.1%. The oscillator also features programmable output level control and an operating temperature range of -40°C to +85°C with a 15 years life cycle guarantee. The working principle of the SIT3809AC-C-25NY is based on a quartz-based resonator that is frequency locked and further tuned to acquire the perfect frequency balance. Finally, the device is also package in hermetic, lead-free packaging that is RoHS compliant.
