Product details

MEMS oscillator replacing a quartz crystal

Unlike a traditional quartz crystal that requires external load capacitors and an inverter, this is a complete oscillator in a 6-SMD package — apply 2.25V to 3.6V and the 25 MHz clock appears on the output pin.

The wide supply range of 2.25V to 3.6V covers both 2.5V and 3.3V logic rails without a separate LDO — useful when the same BOM position must work across multiple board revisions.

The 6-SMD package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many 7x5 mm oscillator pads, so a layout designed for a quartz XO often accepts this MEMS part without a board spin.

No stock-holding claim — availability confirmed at RFQ.

Frequently asked questions

Can I use DSC1121AI3-025.0000 as a drop-in replacement for a quartz crystal oscillator?

This is a complete MEMS oscillator (XO), not a bare crystal. It replaces a quartz-based oscillator module with the same 7x5 mm footprint and CMOS output — no external load capacitors needed. Confirm the Enable/Disable logic polarity matches your existing circuit.
