Product details

41.5 MHz MEMS oscillator with Enable/Disable

The DSC1121AE2-041.5000T is a fixed-frequency MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 41.5 MHz CMOS output with ±25ppm frequency stability across its full -20°C to 70°C operating range. This is useful for system-level power gating or test mode without a full power cycle.

The wide supply range of 2.25V to 3.6V means this oscillator can run directly from a 2.5V, 3.0V, or 3.3V rail without an external LDO — a single BOM line covers multiple logic families. Housed in a 6-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AE2-041.5000T is a surface-mount part suited for automated assembly.

Frequently asked questions

Does the DSC1121AE2-041.5000T have an Enable/Disable function?

Yes — the Enable/Disable function is built in. When the enable pin is de-asserted, the output goes to high-impedance (tri-state) while the oscillator core remains powered, dropping supply current from 35 mA to 22 mA.

Is the DSC1121AE2-041.5000T a CMOS output oscillator?

Yes, the output type is CMOS, making it compatible with standard digital logic inputs without additional level translation.
