Working Principle of SI5338L-B07466-GMR Clock Generator

The SI5338L-B07466-GMR clock generator is highly integrated and can generate a wide range of frequencies from 1 kHz to 400 MHz. Each SI5338L-B07466-GMR device contains two independent clock generators, each with a 10-bit or 12-bit Phase-Locked Loop (PLL) synthesizer core, which generates a variety of clock frequencies based on a programmable reference clock or external clock inputs. The PLL is used to generate a clock frequency with low drift and jitter, and a Voltage Controlled Oscillator (VCO) to control the frequency resolution and output level of the generated clock. The generated clock signals are then routed through a jitter attenuator and a clocking multiplexer (MUX) to achieve the desired output frequency. An input reference reassurance is also provided to protect the jitter attenuator from low-quality input clock signals.

The SI5338L-B07466-GMR also contains a programmable output reference (POR) buffer to support different grades of reference frequencies and clock types, like sine wave, square wave, and Tri-state. Finally, the device contains a fan-out buffer which can output clock signals on up to 32 differential outputs, making it suitable for applications where multiple clock frequencies are required. This allows for the SI5338L-B07466-GMR to be used in a wide variety of communication and industrial applications.

In summary, the SI5338L-B07466-GMR is a highly integrated and feature-rich clock generator and jitter attenuator, designed for use in communication and industrial applications.
