Programmable oscillators are devices that are designed to provide precise and customizable sources of electronic and alternating current (AC) signals at frequencies ranging from a few Hz to several GHz. The SIT9002AI-38N33DD is a single-port, programmable oscillator with an operating frequency range of fmin= 0.1Hz to Fmax = 32GHz. It is an ideal tool for applications that require high accuracy and wide frequency range.

Features

The SIT9002AI-38N33DD programmable oscillator features a wide range of output frequencies and a wide supply voltage range of 2.5V to 3.6V. It also offers excellent phase noise performance with up to -80 dBc/Hz in the 1 MHz to 32GHz range. The oscillator also incorporates a digital control logic, a startup circuit, and a shutoff circuit which can be used to allow the circuit to enter low power sleep mode. This eliminates the need for external components.

Application fields

The SIT9002AI-38N33DD programmable oscillator has a wide range of applications in areas such as communications and signal processing. It can be used as a signal source in various wireless communication systems such as GSM, CDMA, UMTS, WiMAX, LTE, and Wi-Fi. It can also be used for signal processing applications such as spread spectrum and pulse width modulation.

Working principle

The working principle of the SIT9002AI-38N33DD programmable oscillator is based on the use of digital control logic, a startup circuit, and shutoff circuit. The oscillator requires a constant current source for its operation. When input voltage is applied to the oscillator the current source is activated and current flow produces an EMF field which is used to drive the oscillator. The digital control logic, which is connected to the oscillator, then regulates the output frequency and amplitude. The oscillator can be programmed to output a specific frequency by setting the frequency of the input voltage source. The shutoff circuit then reduces the power consumption by switching off the current source when the oscillator is not in use.

Summary

The SIT9002AI-38N33DD programmable oscillator is designed to provide precise and customizable sources of electronic and alternating current signals. It offers excellent phase noise performance, wide frequency range, wide supply voltage range, and other features. Its applications include wireless communication systems, signal processing, and spread spectrum. The working principle of the oscillator is based on the use of digital control logic, a startup circuit, and a shutoff circuit.
