The DSC1121AE1-014.3182T is a 14.3182 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range. AEC-Q100 qualification qualifies this part for automotive applications, though the -20°C to 70°C temperature grade limits deployment to cabin or climate-controlled modules — not under-hood or engine-bay zones where -40°C to 125°C is typical.
The wide supply range of 2.25V to 3.6V allows direct connection to 2.5V or 3.3V logic rails without an intermediate LDO, simplifying power distribution on mixed-voltage boards.
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 footprint is compatible with standard quartz oscillator layouts, easing drop-in replacement in existing designs.
