How it Works

The SI5338A-B08050-GM consists of an integrated synthesizer and PLL for clock generation and jitter attenuation, a local bus for controlling and monitoring the output clocks, and an RF interface for access to the internal clock network. The integrated system works by using the input clock signal to synthesize an output clock frequency with high accuracy and low jitter. The synthesizer and PLL modules allow for the output clock frequency to be adjusted and controlled with the local bus. The internal clock network also allows for the monitoring of all the output clocks.

The device also uses an advanced jitter attenuation algorithm to reduce jitter on the output clocks. The algorithm works by continuously monitoring the jitter on the output clocks and automatically adjusting the internal clock network to reduce the amount of jitter. This ensures that the output clocks have the best jitter performance.
