Programmable Oscillators

Programmable oscillators are available in a variety of frequency ranges and packaging types, allowing users to adjust their oscillator frequency with ease. They can also be used to produce waveforms, such as sine waves, triangular waves, or square waves. Of these, the most popular programmable oscillator is the SIT1602AIE3-25S, which provides significant versatility and cost-effectiveness.

Application Field of SIT1602AIE3-25S

The SIT1602AIE3-25S is an in-phase clock generator that is designed as an all-purpose programmable oscillator. It is used in many applications ranging from communications, embedded systems, and audio/video systems. This programmable oscillator is also well suited for low-noise, low-distortion applications, particularly in mixed-signal applications such as Digital Receivers, TV Tuner and Radio Tuners, TransX Frequency Converters, Digital Cameras and Video Tuners, and Navigation Systems.

Working Principle of SIT1602AIE3-25S

The SIT1602AIE3-25S programmable oscillator is based on crystal-based frequency-selective elements, coupled with a programmable timing generator. This device is capable of generating clock signals with a highly linear frequency versus voltage characteristic, providing excellent precision and accuracy. The programmable oscillator has a two-stage design which includes a wide-range and adjustable frequency generator, and an adjustable phase shifter. The frequency generator uses the crystal-based frequency-selective element and its oscillation frequency is determined by the crystal. The adjustable phase shifter receives signals from the frequency generator, and then adjusts its phase angle according to instructions from the programmable timing generator.

The programmable timing generator is controlled by an EEPROM. This EEPROM stores various configuration parameters such as frequency and phase angle, and also contains data for generating other waveforms such as sine wave, triangular wave, and square wave. With this combination of programmable timing generator and EEPROM, the SIT1602AIE3-25S is capable of producing a wide range of waveforms with varying frequency and phase angles, making it a highly versatile and cost-effective programmable oscillator.

In summary, the SIT1602AIE3-25S is a highly versatile, cost-effective programmable oscillator that is used in many applications ranging from communications, embedded systems, and audio/video systems. Its two-stage design includes a crystal-based frequency-selective element and adjustable phase shifter, coupled with a programmable timing generator to provide a highly linear frequency versus voltage characteristic. The SIT1602AIE3-25S can be used to generate clock signals or waveforms such as sine wave, triangular wave, or square wave, making it an ideal choice for applications with high precision and accuracy.
