Product details

The DSC1001DI1-025.0008T is a 25.0008 MHz XO (Standard) MEMS oscillator from Microchip's DSC1001 series, delivering a CMOS output suitable for direct drive of digital logic inputs. Rated over -40°C to 85°C with ±50 ppm frequency stability, this part is AEC-Q100 qualified, meaning it can be placed on the BOM for engine-bay or cabin electronics without a separate screening step. The 1.8V to 3.3V supply range lets it run off a common 3.3V rail or a low-voltage 1.8V core supply without an extra regulator.

Standby power-down and low-current operation

The standby (power-down) function drops supply current to 15 µA maximum, while active draw is 6.3 mA max — a combination that suits battery-backed modules that wake periodically to transmit or sample.

Frequently asked questions

What is the exact frequency of the DSC1001DI1-025.0008T?

The oscillator outputs a precise 25.0008 MHz CMOS clock signal. This frequency is etched into the MEMS resonator and is not adjustable.

What supply voltage range does the DSC1001DI1-025.0008T accept?

The device operates across a 1.8V to 3.3V supply range, covering the most common digital logic rails in automotive and industrial systems.

What is the standby current consumption in power-down mode?

When the standby (power-down) function is asserted, the supply current drops to 15 µA maximum, preserving battery life in always-on modules.

Is the DSC1001DI1-025.0008T AEC-Q100 qualified?

Yes, the device carries an AEC-Q100 rating, meaning it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. It is suitable for under-hood and cabin electronics.
