SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146AI-FD-33E0A33.330000

The SiT5146 is a ruggedized 1 MHz to 60 MHz MEMS Super-TCXO with ±0.5 to ±2.5 ppm frequency stability, designed for high-reliability applications in telecom, GNSS, and industrial systems. It operates across -40°C to +105°C with an extended cold option to -55°C, features a 5.0 mm × 3.2 mm package, and integrates on-chip regulators to eliminate external LDOs. This variant is configured as a DCTCXO with a 3.3 V supply, LVCMOS output, 0.009 ppb/g acceleration sensitivity, and I²C digital frequency control with 5 ppt resolution and up to ±3200 ppm pull range. It supports factory-programmable frequencies in 1 Hz steps and is RoHS and REACH compliant.
