Programmable Oscillators

Programmable oscillators are adjustable or programmable oscillators that can be tuned to specific frequencies and offer the ability to generate accurate and adjustable signals over a wide range of frequencies. They offer several advantages over fixed-frequency oscillators, such as the ability to change the frequency and amplitude of the signal quickly and easily. SIT1602AIL1-33E is one of the types of programmable oscillators.

Application Field

SIT1602AIL1-33E is suitable for a wide range of applications, such as communications, instrumentation, audio, and video systems. It provides consistent signal frequency accuracy and stability, which is critical for applications requiring precision timing. This oscillator can also be used in data acquisition and data transmission systems, digital signal processing (DSP) systems, and other applications where digital timing accuracy and reliability are essential.

Working Principle

SIT1602AIL1-33E is a variable frequency generator that allows adjustments to the frequency of the waveform output. It is composed of a programmable oscillator circuit that is adjustable between the low and high frequency thresholds, and a frequency modulating subsystem. The programming of the oscillator circuit is accomplished by controlling a voltage regulator and then by varying the settings of the frequency modulation subsystem. The output signal is regulated by the programmable oscillator circuit, which also provides signal stabilization to maintain accuracy and signal integrity over time.

The oscillator circuit includes an amplitude-controlled loop, an integrator, and a differential amplifier. The amplitude-controlled loop converts the voltage level of the control signal into a signal-dependent amplitude that is fed back to the oscillator circuit, thus controlling the signal amplitude. The integrator is responsible for converting the signal into a digital signal, which is then passed through the differential amplifier and converted into an analog signal. The frequency modulation subsystem is responsible for adjusting the frequency of the signal output. This frequency adjustment is performed through the adjustment of digital switches and capacitors, which effectively adjust the frequency of the digital signal.

SIT1602AIL1-33E can also be used for generating arbitrary frequency waveforms by using a built-in frequency modulation feature. This feature allows the user to preset the number of frequency steps, or harmonics, that the frequency modulation control can generate. The ability to program up to 16 different frequencies makes the SIT1602AIL1-33E an ideal solution for applications requiring high accuracy and reliability in frequency generation.

In conclusion, SIT1602AIL1-33E is a programmable oscillator that offers accurate and adjustable signal frequency and amplitude generation over a wide range of applications. Its programmable feature allows users to easily adjust the signal frequency and amplitude, making it an ideal solution for applications where precision timing and signal integrity are essential.
