SiTime Corporation Super-TCXOs SiT5346AI-FPG33IEA10.000000

The SiT5346 is a precision MEMS Super-TCXO operating from 1 MHz to 60 MHz with factory-programmable frequency, stability, and pull range, designed for high-reliability defense, avionics, GNSS, and communications applications. It measures 5.0 mm x 3.2 mm in a surface-mount package and offers ±100 ppb frequency stability across the -40°C to +105°C temperature range with a typical frequency slope of ±1 ppb/°C. The device integrates on-chip regulators to eliminate the need for external LDOs, features ultra-low acceleration sensitivity of 0.009 ppb/g, and provides digital frequency control via I2C with 5 ppt resolution. It supports LVCMOS or clipped sinewave output and complies with Telcordia GR-1244-CORE Stratum 3 requirements. The SiT5346 is RoHS and REACH compliant, with Pb-free, halogen-free, and antimony-free construction.
