Product details

The DSC1121CI2-040.0000 is a 40 MHz MEMS-based XO (Standard) from Microchip’s DSC1121 series, delivering a CMOS output with enable/disable function. Its AEC-Q100 qualification means it passed automotive-grade reliability stress at -40°C to 85°C — suitable for under-hood or cabin electronics where a quartz oscillator might drift or fail under vibration.

Operates from 2.25V to 3.6V, covering both 2.5V and 3.3V 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.
