Programmable Oscillators

Programmable oscillators are a type of electronic oscillator designed to solve a range of precision timing problems. They are particularly useful in situations where a fixed frequency or set of frequencies cannot be predetermined, such as in applications where the noise and disturbance of a regular oscillator could interfere with the output. This is why the SIT3809AI-C-33SG is a powerful and sought-after programmable oscillator device.

The SIT3809AI-C-33SG application field and its working principle

The SIT3809AI-C-33SG is a bipolar IC designed to provide a stable, reliable and independent frequency tuning capability in a single IC interface. It works by combining a Programmable Oscillator Core, voltage controlled oscillator (VCO) and Programmable Dual Clock Generator (PDCG).

Programmable Oscillator Core

The SIT3809AI-C-33SG Programmable Oscillator Core has the ability to generate and control a broad range of frequencies up to 33MHz. The core is user adjustable and can be programmed to output any frequency from 0.5Hz to 33MHz in arbitrary steps. It also provides superior stability, with frequency drift of less than 2ppm over a wide temperature range.

Voltage Controlled Oscillator

The SIT3809AI-C-33SG Voltage Controlled Oscillator (VCO) is a low-noise, wide-band linear VCO that can generate any output frequency from 5MHz to 3GHz. It is user adjustable and provides stability, with frequency accuracy of 0.2 ppm / 8 MHz and phase noise of better than -90 dBc/Hz in the 10kHz - 11MHz range.

Programmable Dual Clock Generator

The SIT3809AI-C-33SG Programmable Dual Clock Generator (PDCG) is a versatile programmable clock generator that can generate programmable frequencies ranging from 0.25MHz to 15MHz. It can be used to generate two independent clocks and is capable of accurate frequency synthesis, with low jitter performance.
