SiTime Corporation LVCMOS Ruggedized Oscillators SIT8944BIR83-33SA50.000000

The SiT8944B is a ruggedized LVCMOS/LVTTL oscillator offering frequencies from 1 to 110 MHz with exceptional acceleration sensitivity of 0.1 ppb/g and industry-standard package sizes including 2.0 x 1.6, 2.5 x 2.0, 3.2 x 2.5, 5.0 x 3.2, and 7.0 x 5.0 mm. It operates over an extended temperature range of -55°C to 125°C, is AEC-Q100 qualified, and supports supply voltages of 1.8 V or 2.25 V to 3.63 V with typical current consumption of 3.8 mA at 1.8 V and 4.0 mA at 2.25 V to 3.63 V. Standby mode reduces power to as low as 0.6 µA at 1.8 V. Total frequency stability is as tight as ±20 ppm, with hysteresis of ±2 ppm and 20-year aging of +28 ppm at 85°C. The device meets MIL-STD-883 mechanical shock and vibration requirements, and is RoHS and REACH compliant.
