Product details

10 MHz MEMS oscillator for harsh-environment clocking

The MEMS resonator gives this oscillator an edge in shock and vibration tolerance over quartz, and its 2.25V to 3.6V supply range means it can run directly off a 3.3V or 2.5V rail without an intermediate regulator.

The DSC1121 series includes other frequencies and stability grades; a cross-reference to a different DSC1121 variant would require verifying the BOM's frequency and stability tolerance.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, the footprint is standard for this class of oscillator — the exposed pad underneath aids thermal conduction to the PCB ground plane, which matters when the device is pulling 35 mA max at the supply rail.

Frequently asked questions

Is the DSC1121AM1-010.0000T AEC-Q100 qualified?

Yes, the DSC1121AM1-010.0000T carries an AEC-Q100 rating, meaning it has passed automotive-grade qualification including temperature cycling, ESD sensitivity, and latch-up testing per the AEC-Q100 stress regime.

What is the output type of the DSC1121AM1-010.0000T?

The output is CMOS, compatible with standard digital logic inputs on MCUs, FPGAs, and SoCs operating at the same supply voltage.

Does the DSC1121AM1-010.0000T have an equivalent replacement?

No official pin-compatible replacement or second-source is listed by Microchip for this exact order code. The DSC1121 series includes other frequencies and stability grades; any substitution would require verifying the BOM's frequency, stability, and supply voltage requirements.
