SiTime Corporation LVCMOS Ruggedized Oscillators SIT8944BA-12-33EA33.333330

The SiT8944B is a 1-110 MHz LVCMOS/LVTTL oscillator with an extended operating temperature range of -55°C to 125°C, designed for high-reliability applications such as avionics and telemetry. It is available in industry-standard packages including 2.0 × 1.6 mm, 2.5 × 2.0 mm, 3.2 × 2.5 mm, 5.0 × 3.2 mm, and 7.0 × 5.0 mm. The device operates with supply voltages of 1.8 V or 2.25 V to 3.63 V, drawing 3.8 mA typical at 1.8 V and 4.0 mA typical at 2.25 V to 3.63 V. It features AEC-Q100 Grade 1 qualification, acceleration sensitivity of 0.1 ppb/g, frequency stability as tight as ±20 ppm, and low standby current down to 0.6 µA at 1.8 V. Output is LVCMOS/LVTTL compatible with 45-55% duty cycle and rise/fall times of 1.3-3 ns depending on supply voltage. The part is RoHS and REACH compliant, Pb-free, and halogen-free.
