Product details

The DSC1001CI2-025.0012 is a standard XO (Standard) MEMS oscillator from Microchip's DSC1001 series, delivering a 25.0012 MHz CMOS output with ±25 ppm frequency stability.

For a battery-powered sensor node that sleeps most of the time, this standby current is below the self-discharge rate of a typical coin cell—the oscillator's own draw won't dominate the sleep budget.

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches the standard 3.2 x 2.5 mm oscillator land pattern.

Frequently asked questions

Is the DSC1001CI2-025.0012 compatible with a 3.3V supply?

Yes. The supply voltage range is 1.8V to 3.3V, so it runs directly on a 3.3V rail without an external regulator. The CMOS output swings rail-to-rail, matching 3.3V logic levels.

What is the frequency stability of the DSC1001CI2-025.0012?

The frequency stability is ±25 ppm over the full operating temperature range and supply voltage. For a 25.0012 MHz carrier, ±25 ppm translates to roughly ±625 Hz of absolute frequency error—tight enough for most UART, CAN, and Ethernet clocking applications.

Does the DSC1001CI2-025.0012 have an AEC-Q100 qualification?

Yes, it carries an AEC-Q100 rating, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and cabin electronics where reliability over 15+ years is required.
