Operating from 1.8V to 3.3V, this oscillator can be driven directly from a 1.8V core rail or a 3.3V I/O rail without an external level translator — the wide supply range covers both without a second oscillator variant on the BOM.
The 4-SMD no-lead package (3.20mm x 2.50mm, 0.90mm seated height) is a standard footprint shared across the DSC1001 family, so a layout change for a different frequency in the same series is a simple BOM swap.
Directly influences purchase decision and budget planning.
Determines immediate availability and time-to-market for production.
Critical for design-in validation and datasheet verification.
Ensures proper system integration and avoids electrical mismatch.
Enables sourcing alternatives when primary part is unavailable or for cost savings.
Required for regulatory compliance in many regions and markets.
