Programmable Oscillators

Programmable oscillator is a type of electronic oscillator (sometimes referred to as clock generator or clock oscillator) that is programmed to generate specific kinds of output signals, usually over a frequency range of a few MHz down to a few Hz. With its customizable programmability and accurate frequency-setting capabilities, a programmable oscillator offers higher degree of design flexibility and improved performance over generic, fixed-frequency oscillators.

The SIT3809AC-C-28NZ is a programmable oscillator that is ideal for communications, embedded, and instrumentation applications. It is a compact, high-precision device that offers excellent performance in terms of accuracy, frequency stability, and signal quality. The SIT3809AC-C-28NZ features a low output frequency range of 1 Hz to 80 MHz, and a low startup frequency of 0.05 Hz. It also features adjustable duty cycle and duty cycle control, which makes it ideal for applications that require precise timing signals.

The working principle of the SIT3809AC-C-28NZ is based on a combination of analog and digital circuitry. Digital circuitry is used to process and store the frequency and parameter settings within the oscillator, and analog circuitry is used for frequency generation and correction of associated drift. The analog circuit converts a digital setting into an analog voltage that is proportional to the desired frequency. This voltage is then used as control voltage for the oscillator circuit. The circuit is designed to react to any changes in the control voltage, allowing for precise and accurate frequency control.

The SIT3809AC-C-28NZ programmable oscillator is commonly used in radio frequency (RF) communication systems, automotive electronics, test and measurement equipment, medical instrumentation, and industrial applications. In these applications, the oscillator is used to generate precise, stable clock signals that are used to drive electronics components such as microcontrollers and logic circuits. It is also used in frequency synthesis systems in which a fixed-frequency oscillator is used to generate a range of output frequencies.

The SIT3809AC-C-28NZ programmable oscillator is a reliable, low-cost device that is ideal for a wide range of applications. It offers superior performance with high accuracy and small size, making it a preferred choice among designers. Its frequency range, low startup frequency, and adjustable duty cycle make it suitable for a variety of applications, from RF communications to embedded systems.
