Programmable oscillators are a type of oscillator used in a variety of applications, particularly when precise frequency and phase stability are required. The SIT9005ACR2D-28NL is one such oscillator capable of achieving accurate frequency and phase stability in a wide range of applications. This article will provide an overview of the SIT9005ACR2D-28NL’s application fields and its inner working principle.

With a frequency range of 9.5 ~ 28MHz, the SIT9005ACR2D-28NL is a good candidate for applications such as clock synthesis, jitter attenuation, frequency agility and test instrumentation. In clock synthesis applications, the SIT9005ACR2D-28NL can be used to accurately generate clock signals of various frequencies and phases. Furthermore, its low jitter of only 3ps makes it ideal for applications where accurate timing information is needed. In jitter attenuation applications, the SIT9005ACR2D-28NL can be used to minimize jitter in data signals passing through the oscillator, allowing for reliable transmission. In frequency agility applications, the SIT9005ACR2D-28NL can be used to quickly and accurately tune the frequency of the oscillator, allowing for efficient and versatile operation. Finally, in test instrumentation applications, the SIT9005ACR2D-28NL can be used both as a signal generator as well as a low-jitter clock source.

The SIT9005ACR2D-28NL utilizes a Phase Locked Loop (PLL) circuit to precisely lock it to a given frequency. In essence, the SIT9005ACR2D-28NL works by comparing the output of a PLL generator to a reference frequency. If there is an error, the PLL generator adjusts its output frequency until the error is minimized. This process is then continuously repeated to ensure that the PLL output remains at the desired frequency and phase despite any external disturbances. This makes sure that the SIT9005ACR2D-28NL can accurately generate the frequencies and phases it is intended to generate.

The SIT9005ACR2D-28NL also offers a number of features to help maximize accuracy. It has an output pulse width adjust feature which allows for adjustable start-up and shut-down times, giving the user control over how quickly the PLL will lock to the desired frequency. The SIT9005ACR2D-28NL also has a slew rate adjustment feature which can be used to adjust the speed of the PLL’s output frequency tracking. This allows the oscillator to more effectively follow the reference signal and thus further reduce the amount of jitter in the output signal.

The SIT9005ACR2D-28NL uses a 4-wire serial interface to set up the PLL’s parameters and to control the oscillator’s frequency and phase locking. This serial port allows for fast and simple programming as well as improved performance when compared to traditional analog PLLs. Furthermore, the SIT9005ACR2D-28NL is RoHS compliant and can operate from -40°C to +105°C, allowing it to be used in a variety of temperature-sensitive applications.

In conclusion, the SIT9005ACR2D-28NL is a programmable oscillator capable of accurate frequency and phase stability over a wide frequency range. It has a number of features which can be used to maximize accuracy, including pulse width and slew rate adjustment, as well as a simple 4-wire serial interface for programming. The SIT9005ACR2D-28NL is well suited for applications such as clock synthesis, jitter attenuation, frequency agility and test instrumentation, and its wide operating temperature and RoHS compliance make it suitable for use in many temperature-sensitive applications. As such, the SIT9005ACR2D-28NL is a good choice for those looking for a reliable and versatile oscillator.
