SiTime Corporation Super-TCXOs SiT5348AICFR-30E0A20.000000

The SiT5348 is a precision MEMS Super-TCXO designed for aerospace and defense applications, offering ±50 ppb frequency stability over the temperature range of -40°C to 105°C with a 5.0 mm × 3.2 mm ceramic package. It features an integrated I2C interface for digital frequency control with 5 ppt resolution and a pull range up to ±3200 ppm, along with on-chip regulators that eliminate the need for an external LDO. The device supports LVCMOS or clipped sinewave outputs, operates at supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V, and meets RoHS and REACH compliance. It is engineered for high shock survivability exceeding 30,000 g and exhibits acceleration sensitivity of 0.1 ppb/g or 0.009 ppb/g depending on configuration.
