Programmable Oscillators

Programmable oscillators are an integral part of applications ranging from communication systems to medical and aerospace devices. In order to control multiple processes and keep them running smoothly, oscillators are employed in various systems. To meet the rapidly changing needs of an ever-expanding technology base, oscillators need to be reliable and versatile. SIT9002AI-13N33ED offers a programmable oscillator in a highly-integrated IC package with exceptional performance over a wide frequency range.

SIT9002AI-13N33ED Overview

The SIT9002AI-13N33ED is a 15-bit programmable oscillator that provides high accuracy and low jitter performance. It is designed to interface to the MCU, eliminating the need for additional components such as resistors, capacitors, and pull-up/pull-down buffers. The oscillator requires very low start-up current and offers an adjustable reference frequency as low as 800 kHz. The oscillator also supports various types of devices, including digital, analog, and microprocessor (μC) systems.

SIT9002AI-13N33ED Application Fields and Working Principle

SIT9002AI-13N33ED is suitable for a wide range of applications, particularly those that depend on precise, reliable oscillations for critical or unpredictable conditions. In digital communication systems, the oscillator can be used to maintain important timing and synchronization. As part of a medical device, it may be employed to provide a continuous source of control over small, time-sensitive operations. Its high responsiveness and low jitter make it an ideal candidate for aerospace applications.The oscillator functions by using an internal charge pump circuit that controls the voltage on an internal capacitor. As the capacitor charges and discharges, it produces a square wave output with a pre-set frequency, determined by the charge pump frequency and the size of the capacitor. The frequency of the output signal can be programmed by setting the charge pump frequency. The on-chip clock can be programmed and monitored through an SPI interface.

Conclusion

The SIT9002AI-13N33ED programmable oscillator provides accurate and reliable oscillation over a wide frequency range and is an ideal candidate for applications that demand precise timing. With its low current operation, high performance, and low jitter, it is ideal for digital communication, medical devices, and aerospace systems.
