SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146ALCFK133JMA10.000000

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 precision GNSS systems. It features a 5.0 mm × 3.2 mm package, operates from -40°C to +105°C, and offers an ultra-low acceleration sensitivity of 0.009 ppb/g. The device supports LVCMOS output, operates at 3.3 V supply, and includes on-chip regulators to eliminate the need for an external LDO. It is factory-programmable and configured as a DCTCXO with I2C interface, enabling digital frequency control with ±10 ppm pull range and 5 ppt resolution. The part is RoHS and REACH compliant, with a clipped sinewave output option available.
