SiTime Corporation Ruggedized MHz Super-TCXOs SIT5348AICFR-30VTA10.000000

The SiT5348 is a precision MEMS Super-TCXO designed for aerospace and defense applications, offering ±50 ppb frequency stability from -40°C to 105°C with an acceleration sensitivity of 0.009 ppb/g or 0.1 ppb/g and shock survivability exceeding 30,000 g. It is housed in a 5.0 mm x 3.2 mm ceramic package and supports supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V. The device features an LVCMOS output, on-chip power regulators eliminating the need for external LDOs, and a VCTCXO configuration with voltage-controlled frequency tuning. It is RoHS and REACH compliant, with a clipped sinewave or LVCMOS output option, and operates across 1 MHz to 60 MHz in 1 Hz steps.
