Product details

The DSC1004BI2-025.0000T is a 25 MHz MEMS-based oscillator from Microchip's DSC1004 series, delivering a CMOS output in a 4-VDFN package. Its ±25 ppm frequency stability covers most general-purpose timing needs, and the wide supply range of 1.7V to 3.6V lets it run directly from 1.8V, 2.5V, or 3.3V rails without an extra regulator.

Standby function and low-power operation

Active draw is 6.5 mA max at 25 MHz — the MEMS resonator consumes less than a quartz equivalent at this frequency, which matters for thermally constrained enclosures.

Frequently asked questions

What is the frequency stability of the DSC1004BI2-025.0000T?

This is typical for a general-purpose XO and covers most microcontroller, FPGA, and interface clocking needs without additional temperature compensation.

Is the DSC1004BI2-025.0000T a direct replacement for a standard 25 MHz quartz oscillator?

Yes, in most cases. It is a drop-in MEMS replacement for a 25 MHz quartz XO with CMOS output in a 5.0 mm × 3.2 mm footprint. The MEMS resonator has faster startup and better shock/vibration tolerance than quartz, but the electrical interface — supply, output, enable — is the same. Confirm the pinout matches your existing quartz oscillator's footprint; the DSC1004 uses a standard 4-pin VDFN layout.

Does the DSC1004BI2-025.0000T support 3.3V operation?

Yes. The supply range is 1.7V to 3.6V, so 3.3V is within spec. The CMOS output swings rail-to-rail at 3.3V, meeting the VIH/VIL thresholds of 3.3V logic families.

What is the standby current consumption of the DSC1004BI2-025.0000T?

15 µA max when the Standby (Power Down) function is asserted. This is low enough for battery-backed real-time clocks or wake-up circuits where the oscillator must idle without draining the cell.
