The 1.8V to 3.3V supply range means a single BOM line covers 1.8V, 2.5V, and 3.3V logic rails — no separate oscillator variants needed when the core voltage changes between board revisions.
The 4-SMD no-lead exposed pad package (7.00 mm x 5.00 mm, 0.90 mm seated height) is a standard footprint for MEMS oscillators; the exposed pad aids thermal transfer to the PCB ground plane.
Frequency determines timing accuracy in the application.
Ensures compatibility with the system power rail.
Automotive grade validation is critical for vehicle electronics.
Direct cost impacts bill of materials budgeting.
Availability affects production schedule and lead time.
Ensures continuity if the part becomes unavailable or needs alternatives.
