Working Principle

The SI5338B-B05493-GMR Clock/Timing - Application Specific product is based on four-channel Silicon Labs Si535B-B05493-GMR timing solutions. It features a specialized on-chip oscillator with a MEMS-based temperature compensated crystal (TCXO) that is used to produce a stable and jitter-free clock source. The device includes an ultra-low-jitter Phase Locked Loop (PLL), which is used to convert the input clock frequency into four different output frequencies.

The PLL works by first loop the input frequency to the reference clock, and then uses the on-chip digital phase-locked loop to convert it into four different output frequencies. The on-chip oscillator is designed to work over a wide temperature range, so the clock output will be stable and consistent even in the presence of temperature variations.

The device also features integrated programmable logic to configure the output frequencies, output drive strength, switching thresholds and more. The output differential clock signals have a clean rise and fall time and minimal phase jitter, resulting in improved system phase accuracy and signal integrity.
