Product details

MEMS oscillator with dual 130 MHz CMOS outputs

The supply voltage spans 2.25V to 3.6V, so the same BOM line works across 2.5V and 3.3V rails without a separate regulator or level translator.

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a height of 0.90 mm, the DSC2311KI2-R0029T fits under low-profile enclosures and alongside dense BGA devices. Current draw in disable mode is a maximum 23 mA, so pulling the enable pin low cuts the oscillator's supply current while keeping the rail alive for other loads.

Supplied on Tape & Reel (TR), which is the standard carrier for automated pick-and-place assembly.

Frequently asked questions

Is DSC2311KI2-R0029T a direct replacement for a standard quartz oscillator?

Yes, it is a drop-in functional replacement for a 6-pin CMOS XO with the same footprint and output type. The MEMS resonator inside is more shock-tolerant than a quartz crystal, but the electrical interface — CMOS levels, enable/disable pin, supply range — matches standard oscillator behaviour.

Does DSC2311KI2-R0029T have an enable/disable function?

Yes, the function is listed as Enable/Disable. Pulling the enable pin low disables both CMOS outputs and drops the supply current to a maximum of 23 mA.
