Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without a separate regulator. For battery-powered or thermally constrained designs, budget this draw into the power rail sizing. ## Package and board layout: 6-VDFN exposed pad Housed in a 6-VDFN exposed-pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The 7.00mm x 5.00mm footprint is larger than a typical 5.0mm x 3.2mm quartz oscillator — confirm the pad layout matches the BOM position before committing the board. Listed as Active by Microchip Technology. No official second source or pin-compatible cross-reference is documented. The DSC1121 series is a single-sourced Microchip MEMS oscillator line; a board spin would be required to substitute a quartz-based XO with a different footprint.","metaTitle":"DSC1121AM1-027.0000T MEMS XO 27 MHz CMOS -55°C to 125°C","metaDescription":"Microchip DSC1121AM1-027.0000T MEMS oscillator, 27 MHz CMOS output, ±50 ppm stability, -55°C to 125°C, 6-VDFN package.
