When disabled, the oscillator draws 22 mA max; active draw is 35 mA max. Supply range spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator. The wide input tolerance simplifies BOM consolidation across multi-rail boards. The 6-SMD no-lead footprint is a standard ceramic oscillator layout — no special via-in-pad or thermal pad requirements.","metaTitle":"DSC1121BM1-027.0000T MEMS Oscillator","metaDescription":"DSC1121BM1-027.0000T: 27 MHz MEMS XO, CMOS output, AEC-Q100, -55°C to +125°C.
