The SI5335A-B05618-GM is a low-power, advanced clock generator and clock jitter cleaner part that can generate up to five outputs of varying frequencies with extremely low noise and jitter performance. It is a popular device used in a diverse range of clock applications, such as low-speed FPGAs, high-end servers, network switches and routers, and big data analytics. This article explains the application field and working principle of SI5335A-B05618-GM.

The application fields of SI5335A-B05618-GM include distributed feedback oscillators (DFBs), clock synthesizers, and clock conditioners. DFBs are used to generate frequencies with high stability, low noise and low jitter for clock and data signals. SI5335A-B05618-GM can produce fixed frequency square wave output clocks with very low jitter performance and low power consumption. Clock synthesizers are commonly used to generate variety of frequencies from a single base frequency at relatively high accuracy. SI5335A-B05618-GM can generate up to five outputs with very low jitter over a wide frequency range. Clock conditioners use jitter cleaning techniques to reduce any external clock noise or jitter that may occur, and then provide an output clock signal with improved signal integrity. SI5335A-B05618-GM provides a low-jitter clock signal with excellent signal integrity.

SI5335A-B05618-GM is a fully integrated, low-power, high-performance clock generator and jitter cleaner, which features advanced DSPLL, jitter cleaning and low frequency harmonic folding technologies. Its DSPLL consists of a low-noise VCO combined with a digital control loop to generate a highly stable and accurate frequency and to clean up any clock jitter. The DSPLL supports a wide variety of frequency generators, including Crystal Oscillators, BOSC (Beats Oscillator Synchronization Clock), DR (Digital Reference) and MMBTS (Modular Multi-Band Tuning Systems). The jitter cleaning technology of the device enables it to significantly reduce any external jitter on the input clocks, while its low frequency harmonic folding technology ensures that the output performance is not compromised even under the harshest environmental conditions.

The main objective of SI5335A-B05618-GM is to improve the frequency accuracy, phase noise and jitter of clocks. It utilizes a digital loop filter to compensate for phase noise and jitter and a phase-locked loop (PLL) to achieve independent control of frequency and phase. Furthermore, a uniform gain update algorithm and a discriminator-based phase detector are employed in order to ensure an optimal lock over the entire operating frequency range. The device also offers four differential output pairs as well as differential or single-ended inputs.

In summary, SI5335A-B05618-GM is a highly versatile and low-power clock generator and clock jitter cleaner part that can be used in a variety of applications such as FPGAs, servers, routers and big data analytics. Its advanced technologies enable it to generate accurate, stable and low-jitter output clocks with excellent signal integrity. It is easy to integrate into circuits and offers very low power consumption.
