Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external LDO; the wide range simplifies power-tree design across mixed-voltage boards.
The exposed-pad package (7.00 mm × 5.00 mm, 0.90 mm seated height) is a standard footprint shared by many MEMS and quartz oscillators.
RoHS compliance is standard for Microchip's DSC1121 series; the part is lead-free and suitable for RoHS-sensitive BOMs.
