Programmable Oscillators are electronic devices that produce a periodic signal with a particular frequency. The frequency of the signal can be controlled and programmed, commonly using software or digital resources. These oscillators are used in many applications such as data communication, wireless communication, radio frequency transceiver systems and timing circuits. One of the most common types of Programmable Oscillators is the SIT9002AC-28N25DB.

The SIT9002AC-28N25DB is a CMOS-based programmable oscillator manufactured by Silicon Labs. This device is capable of producing high stability oscillations up to 25 MHz frequency. It features an adjustable frequency range of 25 to 614 KHz and an operating temperature range of -40 to +85 degrees Celsius. It is designed to operate from a 2.5V supply voltage. It has an output disable function that can be used to turn the output off to save power. The device also features a programmable square wave output and a programmable duty cycle. The SIT9002AC-28N25DB has a low current consumption of only 56uA when operating from a 2.5V supply and a low leakage current of 0.7 mA.

The SIT9002AC-28N25DB is commonly used in applications such as radio transceivers, sensors, digital clocks, automotive systems and energy harvesting. The device is most commonly used in systems that require low power yet high precision timing applications.

The device also offers excellent timing accuracy, improved jitter performance, and high phase-noise performance.

The SIT9002AC-28N25DB is based on the principles of crystal oscillators. The device is composed of two inverters connected in series. An external quartz crystal is connected between the two inverters. The quartz crystal generates an electrical oscillation with a precise frequency and the voltage of the quartz crystal is controlled by the two inverters. The output of the quartz crystal is converted to a linear form using a transformer or an amplifier. This signal is then used to control the output oscillations on the SIT9002AC-28N25DB. The output frequency of the oscillator can be programmed using a selection switch or using a programming voltage.
