SiTime Corporation Ruggedized MHz Super-TCXOs SiT5146AE-FK-33E0B50.000000

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, wireless, and GNSS systems. It operates from -40°C to +105°C with an extended cold option down to -55°C, features a 5.0 mm × 3.2 mm surface-mount package, and integrates on-chip regulators to eliminate the need for an external LDO. The device supports LVCMOS or clipped sinewave outputs, with a supply voltage of 3.3 V ±10%, and delivers ultra-low acceleration sensitivity of 0.009 ppb/g. It is RoHS and REACH compliant, with no activity dips or micro jumps, and is resistant to shock, vibration, and board bending.
