Programmable oscillators refer to oscillators whose characteristics such as frequency and stability can be changed by programming. The technology has been widely used in circuit design from the analog world to the digital world. One of the most commonly used programmable oscillators is SIT9002AI-48N25DB. This article will discuss the application field and working principle of SIT9002AI-48N25DB.The SIT9002AI-48N25DB was designed by SiTime Corporation, a leader in MEMS timing technology. It is a digital programmable oscillator (DPO) with a frequency tuning range of 25 to 175 MHz and a tuning accuracy of 0.5 ppm. The device has a wide frequency range and high sectional stability, making it ideal for use in applications that require precise clock synchronization and reliable timing control.In terms of its application field, the SIT9002AI-48N25DB is widely used in consumer electronics such as personal computers, audio and video equipment, mobile phones, and navigation equipment. It is also used in communication systems such as base stations and backbones, and industrial applications such as automotive, aerospace, medical, and industrial controls.The working principle of the SIT9002AI-48N25DB is based on temperature compensation. The device consists of a quartz crystal resonator and a temperature coefficient generator (TCG). The TCG provides a feedback signal that is proportional to the resonator temperature. This signal is used to adjust the resonator frequency in order to compensate for temperature drift. The advantage of this approach is that it eliminates the need for an external compensation capacitor, making the circuit simpler and more reliable.In addition, the SIT9002AI-48N25DB has an embedded digital encoder that allows for one-step tuning controller configuration. This allows the device to be programmed to change its oscillation frequency in response to external events or commands. Additionally, the device also comes with integrated power control and automatic power-on reset (POR) functions.To summarize, the SIT9002AI-48N25DB is a digital programmable oscillator with a wide frequency range and high sectional stability. Its temperature-compensated design eliminates the need for an external compensation capacitor, making it ideal for a wide range of applications that require precise timing control and reliable clock synchronization. It is also equipped with an embedded digital encoder and integrated power control and POR functions.The specific data is subject to PDF, and the above content is for reference
