SiTime Corporation Ruggedized MHz Super-TCXOs SiT5349AC-FR-25E0A220.000000

The SiT5349 is a 60 MHz to 220 MHz, ±50 ppb precision MEMS Super-TCXO in a 5.0 mm × 3.2 mm package, designed for high-reliability defense, space, avionics, and GNSS applications. It features acceleration sensitivity of 0.009 ppb/g or 0.1 ppb/g, shock survivability above 30,000 g, and on-chip regulators that eliminate the need for external LDOs. The device supports LVCMOS output and offers three configurations: TCXO, VCTCXO, and DCTCXO with I2C digital frequency control down to 5 ppt resolution, allowing pull ranges up to ±3200 ppm. It operates at 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply voltages, and complies with RoHS and REACH standards. Frequency stability is ±50 ppb over temperature, with a typical ΔF/ΔT of ±1 ppb/°C and 1.5e-11 ADEV at 10 seconds averaging.
