Product details

MEMS oscillator for 25 MHz CMOS timing

The DSC1033BE2-025.0000T is a 25 MHz MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a CMOS output at 3.3V supply with ±25 ppm frequency stability over -20°C to 70°C.

Active current draw is 3 mA typical at 25 MHz — a low-power choice for a 3.3V CMOS clock source in portable or thermally constrained designs.

Housed in a 4-SMD no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint for 25 MHz oscillators, compatible with reflow soldering.

Frequently asked questions

What is the output type and supply voltage of DSC1033BE2-025.0000T?

The output is CMOS, and the supply voltage is 3.3V.

What does the standby (power down) function do?

When the standby pin is asserted, the oscillator stops its output and draws only 1 µA max from the supply — effectively gating the clock while preserving the MEMS resonator state for a fast restart.

How does this MEMS oscillator compare to a traditional quartz oscillator?

The MEMS resonator is inherently more resistant to shock and vibration than a quartz crystal, and typically offers faster start-up. The DSC1033BE2-025.0000T delivers ±25 ppm stability — comparable to many quartz XOs — in a standard 4-SMD package.
