Supply voltage range is 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator — the wide tolerance simplifies BOM consolidation across mixed-voltage designs. ## 6-SMD package and board integration Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — this is a standard footprint that matches many quartz oscillator pads, easing drop-in replacement.","metaTitle":"DSC1121AM1-100.0000 MEMS XO, 100 MHz, CMOS, -55°C to 125°C","metaDescription":"Microchip DSC1121AM1-100.0000: Active MEMS oscillator, 100 MHz CMOS output, ±50 ppm stability, 2.25V-3.6V supply, -55°C to 125°C.
