SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146AICFK-28N0A40.000000

The SiT5146 is a 1 MHz to 60 MHz MEMS Super-TCXO with ±0.5 ppm frequency stability across temperature, designed for high-reliability applications in telecom, GNSS, and industrial systems. It operates from -40°C to +105°C in an industrial extended range, housed in a 5.0 mm × 3.2 mm package. The device includes on-chip regulators to eliminate external LDOs, offers LVCMOS output, and supports a 2.8 V ±10% supply voltage. Acceleration sensitivity is specified at 0.009 ppb/g for ultra-low g-sensitivity, and it features no activity dips or micro jumps. The part is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free.
