Product details

MEMS clock source for 1.8V CMOS logic

The DSC1018DC1-022.0000T is a MEMS-based XO (Standard) that generates a 22 MHz CMOS clock from a 1.8V supply rail — no external quartz resonator or load caps needed on the board. The 4-SMD no-lead package (2.50 mm × 2.00 mm) takes up about the same footprint as a small ceramic cap. Typical supply current is 3 mA at 22 MHz — low enough that the oscillator won't dominate the power budget on a battery-powered board.

Standby power-down for sleep-mode designs

This is the feature that lets a microcontroller or wireless SoC cut the clock to save battery during deep sleep, then wake and restart the oscillator in milliseconds.

Suitable for new designs.

Frequently asked questions

Is the DSC1018DC1-022.0000T compatible with a 1.8V supply?

Yes, it is specified for a 1.8V supply rail — that is the only voltage option listed. The CMOS output swings rail-to-rail, so the clock high level matches the 1.8V logic family.

What are the advantages of a MEMS oscillator over a quartz crystal for this part?

The MEMS resonator is factory-trimmed to frequency — no external load capacitors or feedback resistors. The part is also more resistant to vibration and shock than a quartz crystal, and the 4-SMD package is a standard footprint that reflows without special handling.
