The 2.25V to 3.6V supply range covers 2.5V, 3.0V, and 3.3V rails without a separate LDO — one less component on the BOM.
The 6-SMD No Lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a standard 6-pin land pattern with 0.50 mm pitch; the small footprint frees board area on dense ECU or camera module layouts.
Yes, the DSC1121DI2-125.0000B carries AEC-Q100 qualification, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. It is suitable for under-hood and cabin ECU applications where standard commercial oscillators would not meet the qualification requirements.
