Rated across -40°C to 85°C with ±25 ppm frequency stability, this part suits outdoor telecom base stations, factory-floor PLCs, and engine-bay controllers where a quartz oscillator might drift or fail under vibration. ## Supply rail and power budget Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external LDO. Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.","metaTitle":"DSC1121BI2-012.0000 MEMS Oscillator 12 MHz CMOS - Microchip","metaDescription":"DSC1121BI2-012.0000: 12 MHz MEMS XO, ±25 ppm, CMOS output, 2.25-3.6 V, -40 to 85°C, 6-VDFN.
