Working Principle

The SI5338A-B07015-GM uses a sophisticated PLL (Phase-Locked Loop) architecture that enables quick lock times while providing the best possible jitter performance. A digitally-controlled oscillator (DCO) is used to generate the clock, and a low-noise PLL is used to synchronize the clock with the reference. By dynamically adjusting the resonator frequency, the PLL is able to minimize jitter.

The output of the DCO is further improved by a dual-core loop filter architecture, which reduces jitter in real-time by eliminating frequency drifts. Additionally, the SI5338A-B07015-GM features a low-noise output buffer, to further reduce output jitter.

The SI5338A-B07015-GM features various features to further reduce clock jitter and drift. These features include an adjustable DCO frequency range for better frequency accuracy, adjustable loop bandwidth for better noise rejection, and adjustable slew rate limiter to reduce clock ringing.

Overall, the SI5338A-B07015-GM is an advanced, low-jitter, cost-effective clock generator designed to provide customers with the best possible combination of jitter performance and cost/performance ratio.
