SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146AE-FD-33VTA40.000000

The SiT5146 is a 1 MHz to 60 MHz MEMS Super-TCXO with ±0.5 to ±2.5 ppm frequency stability, housed in a 5.0 mm × 3.2 mm package. It features an 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 or clipped sinewave outputs, with a 3.3 V supply voltage and voltage-controlled frequency tuning (VCTCXO) via an analog control input. It is RoHS and REACH compliant, with no activity dips or micro jumps, and is designed for high-reliability applications including precision GNSS and ruggedized communications. The part has a frequency of 40.000000 MHz, 0.009 ppb/g acceleration sensitivity, 3.3 V supply, and VCTCXO operation.
