SiT8924B: AEC-Q100 Oscillator with -55°C To 125°C Temp Range

E-mail Print

The SiT8924B is the most reliable and the highest quality AEC-Q100 compliant oscillator for automotive and extreme temperature applications. This device provides a perfect combination of the widest frequency range (1 MHz to 110 MHz), excellent stability (as low as ±25 PPM) and widest temperature range (-55°C to +125°C) in the smallest 2.0x1.6 mm package that is not readily available from quartz. It also features the industry's best shock and vibration resistance.

The SiT8924 is avaiable in five industry standard packages, and therefore replaces quartz products without any design changes.

Note:12.The voltage portion of the SiT8924 part number consists of two characters that denote the specific supply voltage of the device. The SiT8924 supports either 1.8V ±10% or any voltage between 2.25V and 3.62V. In the 1.8V mode, one can simply insert 18 in the part number. In the 2.5V to 3.3V mode, two digits such as 18, 25 or 33 can be used in the part number to reflect the desired voltage. Alternatively, “XX” can be used to indicate the entire operating voltage range from 2.25V to 3.63V.
