The supply voltage spans 2.25V to 3.6V, so it runs directly from a 2.5V or 3.3V rail without an intermediate LDO — one less component on the BOM.
The 6-SMD, No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm — a standard footprint that matches many quartz XO packages, easing a drop-in replacement during a MEMS migration.
It operates from 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an external regulator.
No official second-source or replacement is listed. The DSC1121 series shares the same footprint and pinout across frequencies; a different frequency in the same series is a direct swap if the BOM clock tree allows.
