SiT5349 Datasheet

The SiT5349 is a ruggedized ±50 ppb precision MEMS Super-TCXO with a maximum acceleration sensitivity of 0.009 ppb/g or 0.1 ppb/g. Engineered for best dynamic performance, the SiT5349 is ideal for high reliability defense, space, avionics, guidance, precision GNSS and communications applications.

Leveraging SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technologies, the SiT5349 delivers the best dynamic performance for timing stability in the presence of environmental stressors such as air flow, temperature perturbation, vibration, shock, and electromagnetic interference. This device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.
