SiTime Corporation Super-TCXOs SiT5349AE-FR033ITB125.000000

The SiT5349 is a 60 MHz to 220 MHz, ±50 ppb precision MEMS Super-TCXO in a 5.0 mm × 3.2 mm package. It offers three configurations: TCXO, VCTCXO, and DCTCXO with I²C digital frequency control down to 5 ppt resolution and a pull range up to ±3200 ppm. It has an acceleration sensitivity of 0.009 ppb/g or 0.1 ppb/g, operates reliably under harsh environmental stressors including vibration, shock, and thermal perturbation, and integrates on-chip regulators to eliminate the need for external LDOs. It supports LVCMOS output at 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply voltages and is RoHS and REACH compliant. The device is engineered for high-reliability defense, avionics, GNSS, and space applications with a shock survivability exceeding 30,000 g.
