Programmable Oscillators

Programmable oscillators are oscillators that produce a frequency that can be programmed or modified. They are often used in electronics and radio applications, as well as for research and development.

SIT1602AIL3-25S

The SIT1602AIL3-25S is a high reliability, low power, digitally programmable crystal oscillator that can be used in a variety of applications. It is designed to provide a stable and accurate frequency reference with low jitter and wide dynamic range. It offers an optional adjustment range of 0.5, 1 or 2%, making it ideal for applications requiring precise frequency control.

Application Fields & Working Principle

The SIT1602AIL3-25S is commonly used in communications, medical, and industrial applications as a trigger generator and clock oscillator. Its frequency range is from 10 MHz to 40 MHz and the tuning pin is provided for optional frequency adjustment.

The SIT1602AIL3-25S operates on the principle of a quartz crystal oscillator. It utilizes a quartz crystal which is held between two electrodes. When an alternating current is applied across the crystal, it vibrates at its natural frequency and a voltage will be produced at the output. The output voltage is then amplified by a voltage regulation loop to produce a clean, saturated sine wave.

In addition to its quartz crystal, the SIT1602AIL3-25S contains a frequency divider and a digitally controlled oscillator. The frequency divider provides the ability to precisely control the frequency output by dividing it down from the quartz crystal frequency. The digitally controlled oscillator provides a level of stability and accuracy which is not achievable with a traditional analog oscillator.

Moreover, the SIT1602AIL3-25S also contains a temperature compensated oscillator (TCXO) which ensures that the output frequency remains stable across different temperatures. Temperature stability is critical to applications such as radar and satellite communications.

The SIT1602AIL3-25S is also available in multiple package options including ceramic, plastic and surface mount options for easy implementation into existing circuits. This versatile programmable oscillator is the perfect solution for any application requiring precise frequency control.
