SI5335D-B01799-GMR is a clock generator, phase-locked loop (PLL), and frequency synthesizer from Silicon Laboratories. It is used to generate high-precision clock signals with a wide range of frequencies and ultralow jitter for Frequency Division Multiplexing (FDM) systems, Network Interface Cards (NICs) and communications hardware with stringent jitter requirements. This is an application field for the SI5335D-B01799-GMR frequency synthesizer.

The SI5335D-B01799-GMR features a fast lock time, low power operation, high frequency and low jitter clock signals up to 3GHz output frequency in multiple formats including Industrial Standard (IS) clocks, differential LVPECL and CML outputs. This makes the SI5335D-B01799-GMR an ideal source of signals that are used in many communications systems, including telecoms, networking, transportation, and industrial automation.

The working principle of SI5335D-B01799-GMR is based on a clock generator, phase-locked loop (PLL), and frequency synthesizer. The clock generator and PLL are used in combination to generate a wide range of high-precision clock signals. The input oscillator is used to set the frequency of the clock signal, and then it is multiplied and/or divided with the help of frequency divider, divisors, and NCO blocks to attain the required frequency. The frequency is then compared with the reference oscillator frequency, and this comparison is used to adjust the output frequency toward the desired clock rate.

The frequency synthesizer further refines the output by adjusting the frequency of the output with the help of a sigma-delta modulator, thereby reducing the total jitter and clock skew. The sigma-delta modulator is used to digitally modulate the output frequency, producing a high resolution and low jitter clock signal. The output of the frequency synthesizer is then used to provide the exact clock rate and ultra-low jitter required for FDM systems, NICs, and other communications systems.

The SI5335D-B01799-GMR is thus a valuable component for communications applications, allowing designers to generate high-precision clock signals with wide frequency ranges and low jitter for FDM systems, NICs and other communication hardware with stringent jitter requirements. It utilizes advanced technology, such as sigma-delta modulation, to provide an optimal output frequency, thereby reducing the risk of clock jitter errors and the need for frequent reductions of clock rates.
