The SI5347A-D-GMR is an extremely advanced and reliable clock generator and PLL IC, developed by SiTime Corporation. It is used in a variety of industrial, medical, and consumer grade applications. The SI5347A-D-GMR has a flexible input/output clock configuration that allows for low jitter and selectable output frequencies with low skew. It is also capable of operating at temperature ranges from -40°C to +125°C, making it extremely suitable for harsh environments.

The main applications for the SI5347A-D-GMR are found in digital boards, microcontrollers, and digital signal processors (DSPs). It is particularly useful in Ethernet cards, graphics boards, industrial control systems, and automotive electronics. The device also has powerful capabilities for dealing with system clock noise, meaning it can be used in a wide range of industrial and corporate applications.

The SI5347A-D-GMR has two very important features that make it so effective: an adjustable clock generator and a phase-locked loop (PLL). The adjustable clock generator produces a frequency input, while the PLL uses this signal to process and accurately generate an output frequency. This enables the device to generate very accurate, low-jitter clock signals, even when temperature and other environmental factors vary.

The adjustable clock generator can produce a range of frequencies from the lowest to the highest of the specified frequency range. This enables the PLL to interact with the clock signal and adjust its output frequency accordingly, while also minimizing phase errors caused by environmental fluctuations. The circuitry of the adjustable clock generator is well-protected and robust, ensuring reliable operation.

The PLL of the SI5347A-D-GMR is capable of operating over a wide variety of operating frequencies. It has the ability to synthesize the highest frequency in its range, as well as to detect very small discrepancies in the input clock signal. This ensures the accuracy and stability of the output frequency, while also greatly improving the accuracy of the entire system.

The SI5347A-D-GMR is particularly useful for applications that require low jitter and selectable output frequencies with low skew, as well as for applications that are exposed to harsh temperatures. It is also suitable for applications that require system clock noise cancellation. It is highly reliable and cost-effective, making it an ideal clock generator and PLL IC for a wide range of applications.
