That stability matters when the clock drives a CAN transceiver or an Ethernet PHY — the tight ppm keeps the bit timing within the receiver's sampling window across temperature and supply variation.
Supply range is 1.8V to 3.3V — a single rail that covers both 1.8V-core and 3.3V-I/O logic families without a level translator.
Housed in a 4-SMD, no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. The 0.126" × 0.098" footprint matches the standard 3.2×2.5 mm MEMS oscillator land pattern — no special via-in-pad or thermal pad required, so a two-layer board handles the fan-out.
The DSC1001 series is the base product number; the suffix encodes the specific frequency, stability, and temperature grade.
