Product details

This is not an "automotive-capable" industrial part — it is genuinely qualified to the AEC-Q100 standard.

Supply voltage and output — matching your rail and logic family

The supply voltage range is 2.25 V to 3.6 V, which covers 2.5 V and 3.3 V logic rails common in automotive ECUs and industrial controllers.

The 6-SMD No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — it is a standard MEMS oscillator footprint compatible with common 3.2 x 2.5 mm XO pads. The No Lead construction means no exposed side pads; the solder joint is visible only underneath the device, so X-ray inspection is the standard post-reflow check.

Frequently asked questions

How do I enable or disable the output on DSC1121CI2-066.0000?

The part has an Enable/Disable function on a dedicated pin. Driving the pin high enables the output; driving it low disables the output, dropping the supply current from 35 mA max to 22 mA max. The exact logic threshold and pin assignment are in the datasheet.
