The DSC1121AI2-125.0032T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 125.0032 MHz CMOS clock output with enable/disable control. With AEC-Q100 qualification and an industrial -40°C to 85°C temperature range, this part is specified for automotive ECUs, outdoor telecom, and industrial control where a quartz oscillator would need a larger, more expensive package to meet the same reliability profile.
Rated at ±25 ppm frequency stability, the DSC1121AI2-125.0032T holds the 125.0032 MHz output within a tight window across temperature and supply variation. The supply range spans 2.25 V to 3.6 V — a single part covers 2.5 V and 3.3 V logic rails without a separate regulator.
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 DSC1121AI2-125.0032T fits the standard 7x5 mm oscillator footprint.
