The output frequencies can be predetermined using the integrated frequency dividers or generated using a variety of onboard programming techniques.

The SI5334J-B02374-GMR IC is designed for applications requiring precision frequency generation, jitter specifications, and excellent phase noise correction. It is commonly used in clocking applications such as point-to-point communication, networking and storage systems, test instruments, instrumentation, automated test equipment and control systems, medical monitoring and control instruments, avionics systems and military/aerospace applications.

The working principle of the SI5334J-B02374-GMR is based on its comprehensive fractional-N based mechanism. The fractional-N synthesis produces a very low jitter and noise output frequency using an integrated voltage-controlled oscillator (VCO) over a wide range of frequencies. The output frequency is derived from a simple division of the VCO output frequency and the reference frequency by an integer ratio, which is defined by the digital fractional-N cost factor. The fractional-N cost factor is used to optimize the performance of the IC for the application (in terms of stability and jitter). It is internally pre-programmed for easy configuration, but a range of external programming options are also provided. The IC also includes a simplified design approach which uses two adjustable peak detectors and an internal lock detector circuit to obtain the optimum jitter performance.

The SI5334J-B02374-GMR features a wide input frequency range of 10kHz to 200 MHz, with an output frequency ranging up to 1.155 GHz. It provides a typical jitter performance of 1.22 ps rms and a maximum jitter of 12.2 ps rms. The IC also features a low power consumption of only 6 mW in standby mode and can be powered using a low-voltage battery. Programmable fractional-N synthesis and a wide output frequency range are both provided for easy customization and optimization for specific applications.

The SI5334J-B02374-GMR is a high-precision, application-specific clock generator IC that provides a low phase noise output with jitter standards that exceed the industry standards for the clocking applications. With its integrated jitter attenuation, simple programming techniques, low power consumption, and wide frequency range, the SI5334J-B02374-GMR IC provides an ideal solution for a variety of applications demanding tight accuracy and jitter performance.
