The DSC1121BI2-012.2880T: Supply voltage spans 2.25V to 3.6V, making it compatible with both 3.3V and 2.5V rails without an external regulator.
6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm max — a standard MEMS oscillator footprint that matches many quartz XO land patterns. Surface-mount assembly; the no-lead construction reduces parasitic inductance compared to a gull-wing package at this frequency.
