Product details

40 MHz MEMS oscillator with ±10ppm stability

The DSC1121CL5-040.0000T: Supply voltage spans 2.25V to 3.6V, making it compatible with both 3.3V and 2.5V logic rails without an external regulator. The Enable/Disable function allows the output to be tri-stated for power savings or test mode isolation.

Industrial temperature grade and MEMS reliability

The MEMS base resonator provides inherent shock and vibration tolerance compared to quartz, reducing the risk of startup failures in high-G environments.

Listed as Active by Microchip Technology, the DSC1121CL5-040.0000T remains in ongoing production and is suitable for new designs and volume BOMs. Sourced through independent distribution; quoted to order against the BOM quantity.

6-VDFN package and board layout

Surface-mount assembly on a 2-layer board is straightforward; the small outline saves space in dense clock trees.

Frequently asked questions

Is the DSC1121CL5-040.0000T a MEMS oscillator?

Yes, it uses a MEMS base resonator rather than a quartz crystal, offering improved shock and vibration tolerance.
