Product details

25 MHz MEMS oscillator with ±10 ppm stability

The DSC1121AE5-025.0000T is a 25 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±10 ppm frequency stability across its -20°C to 70°C operating range. The Enable/Disable function lets the system shut off the oscillator when the clock tree is idle, dropping supply current from 35 mA max to 22 mA max.

Package and board-fit notes

Surface-mount assembly on standard FR-4; the exposed pad is the primary thermal path, so the solder paste coverage under it should match the recommended land pattern in the datasheet.

Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

What is the output type of the DSC1121AE5-025.0000T?

CMOS output — it drives standard logic-level loads directly without external termination or level translation.

What supply voltage does the DSC1121AE5-025.0000T require?

It operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails commonly found in embedded systems.
