SiTime Corporation Super-TCXOs SiT5541AE-WU030ITA40.000000

The SiT5541 is a ruggedized super-TCXO oscillator designed for high-precision timing in aerospace and defense applications, offering ±10 ppb frequency stability over the -40°C to 105°C temperature range. It features a 7.0 mm × 5.0 mm ceramic package, operates at supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V, and provides LVCMOS or clipped sinewave outputs. The device integrates on-chip regulators to eliminate the need for external LDOs and exhibits ultra-low acceleration sensitivity of 0.01 ppb/g or 0.1 ppb/g. It supports digital frequency control up to ±3200 ppm and is resistant to vibration, shock, and electromagnetic interference.
