Product details

The DSC1121CI2-040.0000T: AEC-Q100 qualified, this oscillator targets automotive ECU, ADAS sensor, and infotainment clock trees where quartz crystal reliability under vibration and thermal cycling is a concern.

Operates from a 2.25V to 3.6V supply, covering 2.5V and 3.3V logic rails without an external regulator.

Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits the same land pattern as standard 3.2 x 2.5 mm quartz oscillators.
