The SiT5346 is a 1 MHz to 60 MHz precision MEMS Super-TCXO in a 5.0 mm x 3.2 mm package, designed for high-reliability applications in defense, avionics, and precision GNSS systems. It offers ±100 ppb frequency stability across temperature, acceleration sensitivity of 0.009 ppb/g, and integrates on-chip regulators to eliminate the need for external LDOs. The device supports LVCMOS output, operates from -40°C to +105°C, and is fully compliant with Telcordia GR-1244-CORE Stratum 3 specifications. This variant features a 3.3 V supply voltage and a DCTCXO configuration with digital frequency pull control via I2C, enabling ±400 ppm pull range at 5 ppt resolution.
1 to 60 MHz, ±0.1 to ±0.25 ppm precision Super-TCXO
