Product details

Supply voltage range and operating temperature

The supply voltage range spans 1.8V to 3.3V, covering the common digital core and I/O rails — no extra level translator is needed when moving between a 1.8V MCU and a 3.3V peripheral.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, it fits standard oscillator footprints — the 0.276" x 0.197" land pattern is common across many 20 MHz XOs, simplifying a second-source layout. Surface-mount assembly with a 0.90mm max height keeps the profile low enough for mezzanine card or stacked PCB designs.

Frequently asked questions

Is the DSC1001AL1-020.0000T AEC-Q100 qualified?

Yes, it is AEC-Q100 qualified, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up — suitable for under-hood and cabin automotive applications.
