Product details

10 MHz MEMS oscillator with wide supply tolerance

The DSC1121AE1-010.0000T is a 10 MHz MEMS-based oscillator from Microchip Technology's DSC1121 series, delivering a CMOS output with ±50 ppm frequency stability across a 2.25V to 3.6V supply range.

Enable/Disable and package footprint

Housed in a 6-VDFN with exposed pad (7.00mm x 5.00mm footprint, 0.90mm seated height), the package requires a thermal pad on the PCB for heat sinking; the exposed paddle should be connected to the ground plane per the datasheet layout recommendation.

Frequently asked questions

Can I use the DSC1121AE1-010.0000T as a replacement for a 10 MHz crystal oscillator?

Yes, in most cases. The DSC1121AE1-010.0000T is a complete oscillator — it does not require external load capacitors or a separate inverter. It outputs a CMOS-level 10 MHz clock directly. Verify that your circuit expects a CMOS input (not a sine-wave or clipped-sine crystal input) and that the supply voltage is within 2.25V–3.6V.

What is the difference between the DSC1121 and DSC1122 series?

The DSC1121 series (this part) is a standard-performance MEMS oscillator. The DSC1122 series offers enhanced frequency stability options. For the exact DSC1121AE1-010.0000T, the stability is ±50 ppm over -20°C to 70°C.
