The SiT8925B  is the most reliable and the highest quality AEC-Q100 oscillator for high-frequency automotive and other extreme-temperature applications.  This device provides the perfect combination of high frequency (up to 137 MHz), excellent stability (±20 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. This device also features the industry's best shock and vibration resistance.

The SiT8925 comes in five industry-standard packages and therefore replaces quartz products without any design changes.
