Programmable Oscillators are designed for users who require oscillators that can be adjusted or suited for different applications. The SIT3821AC-1B-33NZ is one such programmable oscillator from the Viasystems stable. It is suitable for a variety of applications of varying frequencies, including phase-locked loop (PLL) synthesizers and clock modules.

The SIT3821AC-1B-33NZ is a four-pin programmable oscillator that offers a wide range of volatile frequency adjustment. It operates over the frequency range of 3.3 MHz to 1.13 GHz and delivers a fast settling time with minimal jitter. The device features integrated CMOS logic and has a maximum power dissipation of 200 mW.

The SIT3821AC-1B-33NZ is constructed on a low-voltage complementary symmetric CMOS process, which enables its three independent logical configurations for the output signal. It offers an asymmetrical output, that can be adjusted from 0V to 5V, and a symmetrical output configuration at 2.5V. It can also provide a CMOS track output of 1.25V and 2.5V.

In addition, the SIT3821AC-1B-33NZ comes with an integrated pre-programmed configuration interface, which can be accessed through the three input/output pins. This can be used to adjust the frequency, duty cycle, and output signal type. The built-in voltage regulator allows users to change the output signal type, which makes it suitable for many applications. Furthermore, the oscillator has a start-up time of less than 12 ns, and the frequency can range up to 1.13 GHz with a voltage ranging from 5V to 1V.

The SIT3821AC-1B-33NZ programmable oscillator is ideal for applications that require wide range frequency tuning and low jitter. It is commonly used in PLL synthesizers and clock modules, although it can also be used in Phase-Locked Loops, Discrete Wave Synthesis, Digital filtering and memory control systems.

The SIT3821AC-1B-33NZ has a simple working principle. It utilizes the voltage regulator to obtain a steady voltage output, which is then fed into the oscillator circuit. This creates a sinusoidal output waveform, which is then adjusted by the input/output pins to change the frequency as well as other parameters. Lastly, the device also produces a second output waveform, which can be used for phase-locking or to synchronize the output waveforms of multiple SIT3821AC-1B-33NZ devices.

The SIT3821AC-1B-33NZ is an all-in-one programmable oscillator that provides an adjustable frequency, low jitter and fast settling time. It is suitable for a variety of applications and offers an integrated pre-programmed configuration interface that can be used to adjust the parameters of the device. It is a great choice for users who require a device that adapts to their specific needs.
