AEC-Q100 qualification (Grade 1 implied by the temperature range) means it meets automotive stress tests for thermal cycling, ESD, and early-life failure — suitable for under-hood ECUs and chassis-domain controllers. ## Supply voltage tolerance and output control Operates from a single 2.25V to 3.6V supply, covering both 2.5V and 3.3V logic rails without an external LDO — the Enable/Disable function (pin 1) pulls the output to high-impedance, drawing a maximum 22 mA in the disabled state. The 6-SMD, no-lead exposed-pad package (7.00mm x 5.00mm footprint, 0.90mm seated height) requires a grounded thermal pad on the PCB for best jitter performance — the MEMS die's thermal coupling to the board affects start-up stability below -40°C.","metaTitle":"DSC1121AM2-100.0000 MEMS Oscillator – 100 MHz, CMOS","metaDescription":"Microchip DSC1121AM2-100.0000 XO (Standard) MEMS oscillator, 100 MHz CMOS output, ±25 ppm stability, AEC-Q100, -55°C to +125°C.
