Product details

The DSC1121CM1-012.0000 is a 12 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a CMOS output with enable/disable function.

Supply voltage flexibility and output drive

The 2.25V to 3.6V supply range covers common 2.5V and 3.3V rails without an external regulator. Maximum supply current is 35 mA, with a disabled-mode draw of 22 mA — the enable/disable pin lets the system power down the oscillator when the clock tree is idle.

No pin-compatible second source is listed, but the DSC1121 family includes multiple frequency and stability variants sharing the same 6-SMD footprint.

Frequently asked questions

What is the output type of the DSC1121CM1-012.0000?

CMOS output — it drives standard digital logic inputs directly without level translation.

Can the DSC1121CM1-012.0000 be used with a 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so both 3.3V and 2.5V rails are within spec.

Is the enable/disable function on the DSC1121CM1 active high or low?

The evidence does not specify the polarity. Refer to the Microchip DSC1121 datasheet for the logic level of the enable/disable pin.
