Product details

Supply flexibility and package footprint

Operating from 2.25V to 3.6V, this oscillator spans 2.5V and 3.3V logic rails without a separate regulator — one BOM line serves both power domains. The 7.00mm x 5.00mm 6-SMD package with no-lead exposed pad provides a low-inductance ground path; the pad should be soldered to a solid ground plane for best thermal and EMI performance. Surface-mount assembly with a 0.90mm seated height fits standard pick-and-place processes and dense board stacks.

Listed as Active — this part is in production and suitable for new designs. Lead time and availability confirmed at RFQ.
