The DSC1121CE5-100.0000T is a 100 MHz MEMS-based oscillator (XO Standard) with CMOS output, housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm. It is AEC-Q100 qualified, meaning it meets the automotive IC stress and reliability requirements for use in under-hood and cabin electronics — the OEM auditor will expect PPAP documentation to back this grade. The supply voltage range spans 2.25V to 3.6V, allowing direct connection to 2.5V, 3.0V, or 3.3V rails without an intermediate regulator.

Frequently asked questions
Is DSC1121CE5-100.0000T AEC-Q100 qualified?
Yes, it carries AEC-Q100 ratings, making it suitable for automotive applications where PPAP documentation is required.
Can DSC1121CE5-100.0000T replace a standard 100 MHz quartz oscillator?
Yes, it is a drop-in replacement for a 100 MHz CMOS quartz XO in the same 3.2mm x 2.5mm 6-pin footprint, with the advantage of AEC-Q100 qualification and ±10 ppm stability that many quartz parts do not offer at this frequency.
What is DSC1121CE5-100.0000T's listed type and output?
The type is XO (Standard) and the output is CMOS.
