Operating from 1.8V to 3.3V, the oscillator accepts any common logic rail without an external regulator — a single supply covers 1.8V, 2.5V, or 3.3V domains, simplifying the power tree.
Housed in a 4-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the footprint matches standard 5.0 x 3.2 mm oscillator pads — no layout change from quartz-based XOs of the same size.
The output is CMOS, making it a direct drop-in for digital clock inputs on MCUs, FPGAs, and SoCs that expect a rail-to-rail square wave.
Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up — suitable for under-hood and cabin applications.
The DSC1001BI1 is a sibling in the same DSC1001 series with identical package, supply range, and CMOS output. The difference is in the frequency stability grade or specific frequency — confirm the exact BI1 variant's stability and frequency against your timing budget before substituting.
