SiT3541 Overview
The SiT3541 is a ruggedized, ultra-low jitter, user programmable oscillator with a maximum acceleration sensitivity of 0.1 ppb/g. SiT3541, designed for high reliability applications, offers the system designer great flexibility and functionality in the most demanding environments. The device supports two in-system programming options after powering up at a default, factory programmed startup frequency:.
