Programmable Oscillators are an invaluable tool in the precision instrumentation and timing markets. They are used in a variety of applications, from clocks and watches, to set-top boxes, to medical instrumentation. The most common type is the SIT3822AC-2C-25NB, which has been around for decades.

The SIT3822AC-2C-25NB Programmable Oscillators are primarily used as clocking devices in digital electronic circuits. The frequency can be changed easily and accurately by controlling two analog signals: frequency modulation voltage (FMV) and power control voltage (PCV).

The frequency of the oscillator output is determined by an internal quartz resonator. The FMV signal controls the amount of frequency shift, and PCV controls the oscillator output power. The loop filter provides an analog voltage that corresponds to the frequency which the quartz resonator is oscillating at. This is compared to the FMV signal, and the difference between them is the frequency error. If the two signals are identical, the frequency is known as the center frequency.

The SIT3822AC-2C-25NB Programmable Oscillators provide a wide range of capabilities, including frequency modulation, power control, and frequency range. The frequency range is selectable by setting the FMV signal reference point via a single trim capacitor. This oscillator is designed for applications requiring precision frequency control, such as frequency synthesisers, radio transmitters, digital television systems, and other advanced systems.

The oscillator is also designed to be extremely robust and highly efficient. It is capable of operating from a single-input supply, which reduces power consumption while increasing stability. The FMV and PCV signals are also isolated from the oscillator circuit and noise, further reducing the risk of interference and noise in the system.

The SIT3822AC-2C-25NB oscillator is also very easy to use. It provides a simple, low-cost solution for frequency control, ideal for smaller applications where cost and design complexity are major considerations. This is also why it is widely used in the precision instrumentation and timing markets, as it provides an easy, cost-effective way to achieve accurate timing, even in complex systems.

In summary, the SIT3822AC-2C-25NB Programmable Oscillator is an invaluable tool when it comes to precision timing and instrumentation applications. It provides a wide frequency range, excellent power control, high precision, and low noise, making it ideal for a variety of applications. Its affordability and easy setup make it the ideal choice for many projects, from digital television to medical instrumentation.
