The DSC1121AM2-024.5760 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 24.576 MHz CMOS output with ±25 ppm frequency stability. AEC-Q100 qualification extends its use to automotive under-hood and chassis domains, where the MEMS die withstands shock and thermal cycling better than a quartz resonator.
Supply voltage and output control for BOM simplification
Operating from 2.25V to 3.6V, the oscillator directly interfaces with 2.5V or 3.3V logic rails without an intermediate LDO — one less component on the BOM.
Package footprint and board layout considerations
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AM2-024.5760 fits standard oscillator footprints and reflow profiles for MEMS devices.
