SI5344H-C05139-GMR Clock Generators, PLLs, Frequency Synthesizers

The SI5344H-C05139-GMR from Silicon Laboratories is a Clock Generators, PLLs, Frequency Synthesizers with Frequency 300 MHz to 400 MHz, Supply Voltage Range 1.8 V to 3.6 V, No. of Inputs 4, Number of Outputs 4. The clock generator consist of a low jitter oscillator, optimized to produce a low-jitter clock output at the same frequency as the reference input. This oscillator is integrated into a PLL (Phase Locked Loop), which is driven by the reference clock. In this way, it is possible to control the output frequency of the clock generator, by changing the frequency of the reference clock. The clock generator provides excellent noise immunity, as it is free from any external interference, and is immune to EMI (Electro Magnetic Interference). Additionally, it supports high frequency switching, and can be used in sensitive applications where minimizing jitter is essential.

Working Principle

The SI5344H-C05139-GMR is designed to work with a reference clock signal. The reference clock signal is used to drive a phase locked loop (PLL), which generates its own output clock signal. The frequency of the output clock signal is equal to the frequency of the reference clock, and is used to drive the various applications. The PLL consists of a low jitter oscillator, which is optimized to produce a low-jitter clock output at the same frequency as the reference input. The reference clock can be adjusted externally, enabling the output frequency of the clock generator to be controlled.

The SI5344H-C05139-GMR is also designed to be resistant to EMI. This is achieved through the use of an internal filter which prevents the clock signal from being interfered with by external sources. This ensures that the clock signal is free from any external interference, and is immune to EMI.

The SI5344H-C05139-GMR also supports high frequency switching, which is necessary for sensitive applications where minizing jitter is critical. The clock generator uses a combination of voltage-controlled oscillator (VCO) and PLL techniques, which enable high frequency switching, enabling it to deliver a wide frequency range from 300 MHz to 400 MHz.

Conclusion

The SI5344H-C05139-GMR from Silicon Laboratories is a highly-integrated clock generator, PLL and frequency synthesizer, designed for use in a range of applications including networking and computing systems, high-definition video, digital audio, test and measurement equipment, avionics, and consumer electronics. It consists of a low-jitter oscillator and a PLL, which enables the reference signal to be adjusted externally and the output frequency to be controlled. Additionally, it is EMI-immune, and supports high frequency switching, making it ideal for sensitive applications.
