SiT1618: Standard Frequency, Automotive Temperature Oscillator

E-mail Print
4pin

The SiT1618 is available in 33 standard frequencies and two temperature ranges (ext. industrial and automotive). This device features ±20 PPM stability, super small 2.0x1.6 mm package (4 other packages available), 3.6 mA low power consumption, and best-in-class shock and vibration.

The SiT1618 is 100% compatible with quartz devices in footprint, therefore replaces quartz without any design changes.

For a similar device in a SOT23-5 package, refer to the SiT2018 clock generator.
