MEMS oscillator with AEC-Q100 qualification
The DSC1121AI2-125.0032 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 125.0032 MHz CMOS output with ±25 ppm frequency stability. Its AEC-Q100 rating means it has passed automotive-grade reliability stress — suitable for under-hood or cabin electronics where vibration and temperature cycling exceed commercial quartz limits.
Supply range and disable function
The Enable/Disable function pulls the output to high-impedance state, dropping supply current to 22 mA max — useful for power gating in multi-clock designs.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm, 0.90 mm seated height. Surface-mount assembly with standard reflow profiles.
