SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146AICFD-33E0A50.000000

The SiT5146 is a 1 MHz to 60 MHz, ±0.5 to ±2.5 ppm MEMS Super-TCXO in a 5.0 mm × 3.2 mm package, designed for high-reliability applications in telecom, military communications, and precision GNSS systems. It features ultra-low acceleration sensitivity of 0.009 ppb/g, operates from -40°C to +105°C, and integrates on-chip regulators to eliminate the need for an external LDO. The device supports LVCMOS output, operates at 3.3 V supply voltage, and includes digital frequency pulling via I2C with up to ±3200 ppm range and 5 ppt resolution. It is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free.
