SiTime Corporation Ruggedized MHz Super-TCXOs SIT5146AICFA-33VTB50.000000

The SiT5146 is a 1 MHz to 60 MHz, ±0.5 to ±2.5 ppm MEMS Super-TCXO in a 5.0 mm × 3.2 mm package, designed for high-reliability applications including telecom, GNSS, and military communications. It features ultra-low acceleration sensitivity of 0.009 ppb/g or 0.1 ppb/g, ±0.5 ppm frequency stability across temperature, and operates from -40°C to +105°C with an extended cold option to -55°C. The device integrates on-chip regulators to eliminate external LDOs and offers LVCMOS or clipped sinewave outputs. This variant is a VCTCXO with a 3.3 V supply and ±50 ppm voltage control pull range.
