SiTime Corporation Ruggedized MHz Super-TCXOs SiT5349AN-FR-33E0A61.000000

The SiT5349AN-FR-33E0A61.000000 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 precision GNSS applications. It features an LVCMOS output, operates at 3.3 V, and includes on-chip regulators to eliminate the need for external LDOs. The device offers ±0.009 ppb/g acceleration sensitivity, ±1 ppb/°C typical frequency slope, and 1.5e-11 Allan deviation at 10-second averaging. It supports factory-programmable frequency tuning in 1 Hz steps from 60.000001 to 189 MHz and 208 to 220 MHz, with shock survivability exceeding 30,000 g. The part is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free.
