The wide 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails without a separate regulator — a single BOM line serves multiple power domains.
The MEMS resonator construction provides inherent resistance to 50,000 g shock and 70 g vibration per the DSC1121 series datasheet, exceeding quartz crystal performance in high-reliability environments.
Yes, the DSC1121CL2-027.0000T is RoHS compliant as standard for Microchip's DSC1121 series. No exemption or non-compliant variant is listed in the product documentation.
No pin-compatible equivalent or cross-reference is listed in the product documentation. The DSC1121 series shares the same 6-SMD footprint across frequencies, so a different frequency variant can be substituted without PCB layout changes.
