The SiT95141, SiT95143, SiT95145, SiT95147, and SiT95148 network synchronizers, jitter cleaners / attenuators, and clock generators are highly resistant to shock, vibration, and power-supply noise, making them ideally suited for robust performance in the field. This document provides information about the power supply noise rejection (PSNR) performance of the SiT9514x products. Also provided are layout guidelines and best practices for customers using the SiT9514x parts in their design.
