The Endura™ SiT3541 is an ultra-low jitter, user-programmable oscillator, engineered to deliver high reliability in aerospace and defense applications. This device utilizes SiTime's unique DualMEMS™ temperature sensing and TurboCompensation™ technology to deliver exceptional dynamic performance in harsh environments, making it:
The device supports two in-system programming options:
1) Any-frequency mode to reprogram the clock output to any frequency between 1 MHz to 340 MHz
2) Digitally controlled oscillator (DCO) mode to steer or pull the clock up to ±3200 ppm
Endura SiT3541 is 100% screened through the SiTime Endura™ process flow to provide high reliability.
