The SI5335B-B02002-GMR is a clock generator, a type of frequency synthesizer, that is part of the Clock/Timing category of components made by Silicon Labs. In this article, we\'ll discuss both the application fields and working principle of this clock generator.

Application Fields

The SI5335B-B02002-GMR is designed to operate with both single-ended and differential input clocks. It is particularly useful for applications where high frequency precision and jitter suppression capabilities are needed, such as wireless and multimode network infrastructure, telecom and datacom networks, and military applications. The clock generator also provides flexible control options, such as automatic input selection, forcing, and a thermal reactive loop.

The SI5335B-B02002-GMR can provide accurate, programmable clock signals. It features over 1.5GHz of output frequency range and programmable slew-rate control. Output frequencies can be tailored to meet the specific needs of applications. It offers extensive features and robust performance in small packages.

The SI5335B-B02002-GMR is also capable of universal input frequency and phase locking, making it suitable for multi-mode wireless transceivers. The device contains two Voltage-Controlled Oscillators (VCOs) that can be used to generate multiple clock outputs at the same frequency, eliminating the need for external resonators and additional frequency filtering components.

Working Principle

The core of the SI5335B-B02002-GMR is an integrated frequency synthesizer. It utilizes an advanced phase-locked loop (PLL) architecture. This architecture consists of a divide-by-N circuit, a phase detector, a charge pump, a loop filter, and a voltage-controlled oscillator (VCO). The clock generator is capable of generating output frequencies up to 1.5GHz.

The external clock input is divided by N to produce a reference frequency, which is then compared with the feedback signal from the VCO. Based on this comparison, the phase detector generates an error signal that is applied to the charge pump, which adjusts the output voltage of the loop filter. The output voltage of the loop filter is then used to control the output frequency of the VCO.

The SI5335B-B02002-GMR features an advanced, programmable slew-rate control, which is used to control the reference frequency of the PLL. This helps ensure that the VCO is accurately locked on to the reference frequency and prevents the VCO from exceeding its maximum frequency range. The device also contains two voltage-controlled oscillators (VCOs), which can be used to generate multiple clock outputs at the same frequency, eliminating the need for external resonators and additional frequency filtering components.

In summary, the SI5335B-B02002-GMR is a clock generator, designed to operate with both single-ended and differential input clocks. It features over 1.5GHz of output frequency range and programmable slew-rate control. It is capable of universal input frequency and phase locking, making it suitable for multi-mode wireless transceivers. The SI5335B-B02002-GMR is an integral component in applications such as wireless and multimode network infrastructure, telecom and datacom networks, and military applications.
