SiTime Corporation Ruggedized MHz Super-TCXOs SiT5146AL-FD-25N0A50.000000

The SiT5146 is a 1 MHz to 60 MHz MEMS Super-TCXO with ±0.5 to ±2.5 ppm frequency stability, designed for high-reliability applications in telecom, military, and precision GNSS systems. It features a 5.0 mm × 3.2 mm surface-mount package, operates from -40°C to +105°C, and includes on-chip regulators to eliminate external LDOs. This variant supports LVCMOS output, 2.5 V supply voltage, and ultra-low acceleration sensitivity of 0.009 ppb/g. It has a factory-programmable frequency of 50.000000 MHz and does not support frequency pulling, as indicated by the 'N' pin function. The device is RoHS and REACH compliant, with no activity dips or micro jumps and high resistance to shock, vibration, and electromagnetic interference.
