Programmable Oscillators

Programmable oscillators generally refer to electronic oscillators with powerful frequency-related capabilities. Depending on their use, they can be classified into different types, such as programmable clock oscillators, programmable sine wave oscillators, programmable diamond oscillators, etc. Among these oscillators, the most popular and commonly used ones are programmable clock oscillators.

Working Principle of the DSC6011ME2A-PROGRAMMABLE

The DSC6011ME2A-PROGRAMMABLE is a voltage-controlled programmable oscillator based on a few variations of PLLs. The PLL consists of a voltage-controlled oscillator, phase detector, and loop filter. The oscillator gives the output frequency, the phase detector will compare the phase difference between the feedback and reference signals, and the loop filter will filter out the fluctuation of the output frequency and provide the steady voltage to the voltage-controlled oscillator.

This oscillator consists of several components, including the clock synthesizer, a digitally-controlled oscillator (DCO), a symmetric low-pass filter, a fractional N divider, a phase-frequency detector (PFD), and a voltage-controlled oscillator (VCO). The clock synthesizer enables the oscillator to dynamically generate a wide range of output frequencies over a wide temperature range. The DCO will produce a low-power digital output signal, which will be fed to the PFD and other components. The PFD then compares the phase difference of the output and reference signals, and produces an error signal that is sent to the low-pass filter.

The filtered error signal is then sent to the fractional N divider circuit and the VCO. The divider will modulate the output frequency by Integer N times, to finely control the fractional PLL output frequency. The VCO will convert this input voltage into the required clock frequency.

By properly setting up the PLL and VCO, users can obtain a fine-tuned output frequency with excellent accuracy and stability. This makes it suitable for a variety of applications, such as instrumentation, control systems, frequency measurement, and communication.
