Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator. Housed in a 6-VDFN package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch DFN footprint requires a solder-mask-defined pad and a via-in-pad layout for the centre ground pad — the datasheet shows the recommended land pattern. Surface-mount reflow per JEDEC MSL-1 is typical. ## Temperature grade and deployment fit This oscillator fits indoor equipment, office networking gear, test instruments, and consumer electronics. It is not qualified for -40°C industrial or automotive environments; for those, the DSC1121 series offers extended-temperature variants (check the -CE4 or -CE3 suffix).","metaTitle":"DSC1121CE5-048.0000T MEMS XO 48 MHz CMOS ±10 ppm – Microchip","metaDescription":"Microchip DSC1121CE5-048.0000T MEMS-based XO, 48 MHz CMOS output, ±10 ppm stability, 2.25-3.6 V supply, 6-VDFN package.
