Standard Frequency, High Temperature Oscillator

Login

The SiT1618B is available in 33 standard frequencies, from 7.3728 MHz to 48 MHz, and two temperature ranges, ext. industrial and automotive. This oscillator features ±20 ppm stability, small 2.0 x 1.6 mm package (4 other packages available), 3.6 mA low power consumption, and best-in-class shock and vibration. 

The SiT1618 is footprint compatible with quartz crystal oscillators, making them ideal replacements for quartz devices without design changes.

For a similar device in a SOT23-5 package, see the SiT2018B oscillator.
