Programmable oscillators are electronic circuits used in both commercial and industrial applications to produce a signal of near-perfect accuracy and stability. These oscillators can be used to generate signals of wide range of frequencies, from kHz to MHz and even GHz frequencies. SIT3821AI-1D2-XXXX000.FP0000X is a programmable oscillator that offers the capability to produce signals in the frequency range of 10 MHz – 2.1 GHz with a frequency variation of ±3%.

SIT3821AI-1D2-XXXX000.FP0000X comprises of a digital controller, a synthesizer, an analog output, and a digital to analog output. The digital controller uses advanced digital signal processing technologies to adjust the frequency with greater accuracy and stability. The synthesizer generates the high frequency signals, while the analog output precisely meters the signal with excellent open-loop accuracy and low noise to ensure reliable signal transmission. The digital to analog output converts the QPSK (Quadrature Phase Shift Keying) signal into the exact frequency and amplitude desired.

The SIT3821AI-1D2-XXXX000.FP0000X can be used in various applications, such as consumer electronics, telecommunications, broadcasting, aerospace and defense, automotive, and medical. It is ideal for high-precision signal signal applications as it offers an extended Frequency range and precision performance. In consumer electronics, the oscillator can be used for controlling or stabilizing the output signal frequency from television, radio and other consumer electronics equipment. In telecommunications, the oscillator is used for signal processing applications that require a high precision and stability, such as signal modulation, signal sync and time keeping.

SIT3821AI-1D2-XXXX000.FP0000X has 2 operating modes, one for direct control of the synthesizer and one for direct control of the digital to analog converter or digital to analog mixer. In direct control mode, the command word from the FS_CLK output is sent to the DAC to change the frequency and amplitude of the output signal. The frequency range can be adjusted with 100ppm accuracy and the amplitude can be adjusted with 0.2dB accuracy. The direct control mode allows the user to precisely control the signal output with great accuracy and stability even under high speed and temperature fluctuations.

In the direct control mode, the user also has a wide range of output timing modes, such as pulse width modulation, port mapping and modulation functions. Pulse Width modulation is used to alter the length and shape of the signal to vary its characteristics and control the final output frequency. Port mapping allows the user to select specific ports and map the output frequency and amplitude. Modulation functions allow for multiple variations in the output signal for different frequency requirements.

The SIT3821AI-1D2-XXXX000.FP0000X is an ideal tool for applications requiring high precision, stability and accuracy over wide frequency range. With its digital controller, synthesizer, analog output and digital to analog output, the oscillator offers a wide range of features, support and flexibility for different applications. Furthermore, its direct control mode and output timing modes allow for enhanced control for even the most demanding frequency requirements.
