SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146AI-FD-33E0B50.000000

The SiT5146 is a 1 MHz to 60 MHz ruggedized MEMS Super-TCXO with ±0.5 to ±2.5 ppm frequency stability, designed for high-reliability applications in telecom, military, and GNSS systems. It comes in a 5.0 mm × 3.2 mm package and operates from -40°C to +105°C, with an extended cold option to -55°C. The device features ultra-low acceleration sensitivity of 0.009 ppb/g, on-chip power regulators eliminating the need for an external LDO, and supports LVCMOS output. It is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free. The part number SIT5146AI-FD-33E0B50.000000 corresponds to a TCXO configuration with 3.3 V supply, 50.000000 MHz frequency, and ±2.5 ppm stability.
