10 MHz MEMS XO — what the ratings buy the board
The DSC1121DI2-010.0000 is a 10 MHz MEMS-based oscillator (XO) with a CMOS output, ±25ppm frequency stability, and a 2.25V to 3.6V supply range — it covers 2.5V, 3.0V, and 3.3V logic rails on the same BOM line without a separate regulator. The MEMS resonator (no quartz) means it survives vibration and mechanical shock that would fracture a crystal — a good fit for motor drives, pumps, and portable instrumentation.
Supply voltage and frequency stability — what to check at layout
Supply range 2.25V to 3.6V lets the oscillator share the core or I/O rail of a 3.3V MCU or FPGA without a dedicated LDO — verify the rail noise stays below 50 mVpp at the oscillator pin to keep jitter within the ±25ppm stability window.
Package and footprint — 6-VDFN, 2.50mm × 2.00mm
6-VDFN package, 2.50mm × 2.00mm body, 0.90mm seated height — the 0.50mm pitch lands need a solder-mask-defined pad with a 0.25mm stencil aperture for reliable reflow. Surface-mount only — no through-hole variant. The small footprint frees board space on dense mixed-signal boards where the oscillator sits near the processor.
