Product details

14.3181 MHz MEMS XO — what this oscillator delivers

The DSC1033DI1-014.3181T is a fixed-frequency MEMS-based XO from Microchip's PureSilicon™ series, delivering a 14.3181 MHz CMOS output from a 3.3 V supply rail.

Microchip lists the DSC1033DI1-014.3181T as obsolete. Availability is confirmed at RFQ — there is no guaranteed stock. If your BOM requires a 14.3181 MHz MEMS XO in a 2.5 mm × 2.0 mm 4-SMD package, a board spin may be needed to accommodate an alternative oscillator from the DSC1033 series or another vendor.

The 4-SMD no-lead package measures 0.098" × 0.079" (2.50 mm × 2.00 mm) with a seated height of 0.035" (0.90 mm). Surface-mount placement on a standard 4-pad land pattern — no external load capacitors required for the MEMS resonator. The small footprint suits space-constrained PCBs in portable or densely populated designs.

Frequently asked questions

Is the DSC1033DI1-014.3181T obsolete?

Yes, Microchip lists this part as obsolete. No factory production remains. It is available through independent surplus channels; quantities are lot-specific and confirmed at RFQ.

Does the DSC1033DI1-014.3181T require an external load capacitor?

No. The MEMS resonator is self-contained — no external load capacitors are needed. The oscillator outputs a full-rail CMOS signal directly.
