SiTime Corporation LVCMOS Ruggedized Oscillators SIT8944BA-31-33EA61.000000

The SiT8944B is a ruggedized LVCMOS oscillator offering frequencies from 1 to 110 MHz with accuracy to six decimal places, designed for high-reliability environments. It operates over an extended temperature range of -55°C to 125°C and is AEC-Q100 qualified for automotive applications. The device supports supply voltages of 1.8 V or 2.25 V to 3.63 V, with typical power consumption of 3.8 mA at 1.8 V and standby current as low as 0.6 µA. It features acceleration sensitivity of 0.1 ppb/g and total frequency stability as tight as ±20 ppm. The oscillator is available in industry-standard packages including 2.0 x 1.6 mm, 2.5 x 2.0 mm, 3.2 x 2.5 mm, 5.0 x 3.2 mm, and 7.0 x 5.0 mm. It is RoHS and REACH compliant, with LVCMOS/LVTTL-compatible outputs and optional standby and enable control via pin 1. Functional and environmental ratings are consistent across the Endura™ series variant.
