1 to 110 MHz, High Temperature Oscillator

The SiT8918B provides a perfect combination of wide frequency range (1 MHz to 110 MHz), excellent stability (±20 ppm) and wide temperature range (-40 to 125 °C) in the smallest 2.0x1.6 mmxmm package that is not readily available from quartz. This device also features the industry's best vibration sensitivity, and shock and vibration resistance.

The SiT8918 comes in industry-standard packages and footprints, and therefore replaces quartz without any design changes.

For the same device in a SOT23-5 package, refer to the SiT2018B.
