Operating from 2.25V to 3.6V, this oscillator spans both 2.5V and 3.3V logic rails without an external LDO — one BOM line covers mixed-voltage designs. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, the footprint matches standard 7x5 mm oscillator land patterns — no layout change from a quartz XO of the same size. Surface-mount mounting with the exposed pad provides a low-thermal-resistance path to the PCB copper pour, aiding heat dissipation from the MEMS die and CMOS output driver. No stock-holding claim — each order is sourced per your line-item requirements.","metaTitle":"DSC1121AE1-024.0000 MEMS Oscillator","metaDescription":"Microchip DSC1121AE1-024.0000 XO, 24 MHz CMOS output, MEMS resonator, AEC-Q100 automotive grade, ±50 ppm stability, 2.25V–3.6V supply.
