Product details

The DSC1001DI1-074.2500 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 74.25 MHz CMOS output with ±50 ppm frequency stability. It is rated AEC-Q100, which qualifies it for automotive applications where reliability under temperature and vibration is mandatory. Operating from 1.8V to 3.3V, it draws a maximum of 8.7 mA when enabled and just 15 µA when disabled via the Enable/Disable function — useful for power-cycled automotive modules that need to conserve battery during sleep.

Industrial temperature range and package fit

The 4-SMD, no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that fits tight PCB layouts common in automotive ECUs.

Listed as Active with no end-of-life notice.

Frequently asked questions

Is DSC1001DI1-074.2500 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, making it suitable for automotive-grade applications where the oscillator must withstand the thermal and mechanical stress of under-hood or cabin environments.

Does DSC1001DI1-074.2500 have an enable/disable function?

Yes, the Enable/Disable function lets you shut off the output, dropping supply current to 15 µA max — useful for power-saving modes in battery-backed or ignition-controlled modules.
