Supply voltage spans 2.25V to 3.6V — one part covers both 2.5V and 3.3V logic rails without a separate regulator, and the wide tolerance absorbs rail ripple from a switching converter. Maximum supply current is 22 mA at 100 MHz — a light load for a 3.3V rail, leaving headroom for the rest of the clock tree. Housed in a 6-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — the small footprint frees board space, but the no-lead terminations require a hot-air rework station; a standard soldering iron won't reach the pads under the body. No minimum order restriction — small quantities and prototype volumes are accommodated at RFQ.","metaTitle":"DSC1121CM1-100.0000 MEMS XO – 100 MHz CMOS, -55 to 125°C","metaDescription":"Microchip DSC1121CM1-100.0000 – 100 MHz XO (Standard), CMOS output, ±50 ppm stability, -55°C to +125°C, 6-SMD.
