SiTime Corporation Super-TCXOs SiT5358AN-FR-28VT-26.000000

The SiT5358 is a 1 MHz to 60 MHz ultra-precision Super-TCXO with ±50 ppb frequency stability over -40°C to 105°C, housed in a 5.0 mm x 3.2 mm ceramic package. It features integrated on-chip regulators to eliminate the need for external LDOs, supports LVCMOS or clipped sinewave output, and operates at 2.8 V supply voltage. The VCTCXO configuration enables voltage-controlled frequency tuning with a pull range up to ±10 ppm. The device provides dynamic stability under environmental stressors such as vibration, airflow, and temperature perturbation, with an Allan deviation of 1.5e-11 at 10 seconds and a typical frequency slope of ±1 ppb/°C. It is RoHS and REACH compliant, with Pb-free, halogen-free, and antimony-free construction.
