Product details

MEMS oscillator with dual 26 MHz CMOS outputs

It delivers two identical 26 MHz CMOS outputs from a single die, which saves a second crystal and a clock buffer on boards that need a synchronous clock for two domains — for example, feeding the same 26 MHz to both a Wi-Fi chipset and an MCU.

Industrial temperature grade and wide supply tolerance

The supply range spans 2.25V to 3.6V, so the same BOM line works on 2.5V, 3.0V, or 3.3V rails without a separate LDO — useful when a board has multiple voltage domains and you want one clock part number across all of them.

For procurement, this removes the single-source risk that comes with NRND or obsolete oscillators.

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a 0.90 mm seated height, the footprint is compact enough for space-constrained wireless modules or sensor nodes.

Frequently asked questions

Is the DSC2311KI1-R0051 compatible with 3.3V systems?

Yes — 3.3V is within the 2.25V to 3.6V supply range, and the CMOS output swings rail-to-rail, so it drives 3.3V logic inputs directly.

Can the DSC2311KI1-R0051 replace a quartz oscillator?

Functionally yes — it is a drop-in XO replacement with CMOS output and ±50 ppm stability. The MEMS resonator is more shock- and vibration-tolerant than quartz and typically has shorter lead times, but the pinout and footprint (6-VDFN) must match the board layout.

Does the DSC2311KI1-R0051 have a datasheet?

Yes, Microchip publishes a full datasheet for the DSC2311 series. The datasheet covers the MEMS resonator characteristics, output waveform timing, and application notes for supply decoupling and layout.

Is the DSC2311KI1-R0051 RoHS compliant?

The part is listed as RoHS compliant per Microchip's standard product marking. No conflict-of-evidence entry suggests otherwise.
