SiTime Corporation Ruggedized MHz Super-TCXOs SiT5346AICFP033JRB32.000000

The SiT5346 is a precision MEMS Super-TCXO offering 1 MHz to 60 MHz output frequencies with stability of ±0.1 to ±0.25 ppm, designed for high-reliability defense, avionics, and GNSS applications. It features a 5.0 mm × 3.2 mm package, 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 supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V. The specific variant SiT5346AICFP033JRB32.000000 is a DCTCXO configuration with an I2C interface for digital frequency control, offering ±200 ppm pull range, 0.009 ppb/g acceleration sensitivity, and ±100 ppb stability across temperature.
