SiTime Corporation Ruggedized MHz Super-TCXOs SiT5347AE-FQ-33E0A80.000000

The SiT5347 is a ruggedized MEMS Super-TCXO designed for high-reliability defense, space, avionics, and communications applications, offering frequencies from 60 MHz to 220 MHz in 1 Hz steps with stability of ±0.1 to ±0.25 ppm. It operates across -40°C to +105°C, features LVCMOS output, and integrates on-chip regulators to eliminate the need for external LDOs. The device has a 5.0 mm × 3.2 mm package and meets Telcordia GR-1244-CORE Stratum 3 specifications. With acceleration sensitivity of 0.009 ppb/g or 0.1 ppb/g, it resists environmental stressors including shock, vibration, and EMI. The SiT5347AE-FQ-33E0A80.000000 variant corresponds to a TCXO configuration with 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply voltage options, ±0.1 ppm stability, extended industrial temperature range (-40°C to +105°C), and 12 mm cut tape packaging. On-chip I2C interface enables digital frequency tuning up to ±3200 ppm with 5 ppt resolution, and all variants are RoHS and REACH compliant.
