SiTime Corporation Super-TCXOs SiT5541A-WUC0002

The SiT5541 is a ruggedized precision oscillator offering ±10 ppb frequency stability over the temperature range of -40°C to 105°C, designed for aerospace and defense applications requiring high dynamic stability under vibration, shock, and thermal shock. It operates from 1 MHz to 60 MHz with LVCMOS or clipped sinewave outputs, integrates on-chip power regulators to eliminate external LDOs, and is housed in a 7.0 mm × 5.0 mm ceramic package. Acceleration sensitivity is specified at 0.1 ppb/g for the 'B' variant, and digital frequency control supports up to ±3200 ppm. The device supports I2C programming and is factory programmable for frequency, voltage, and pull range without custom lead times.
