Standard Frequency, High Temperature Oscillator
LoginThe 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.

Configurable FlexEdge drive strength reduces EMI by slowing rise/fall time – for example the 11th clock harmonic is reduced by 35 dB by increasing the rise/fall edge from 5% to 45% of the period
±20 ppm over automotive temp. (-40 to 125 °C)
- Better timing margin ideal for outdoor and high-temp operating environment
