Why this MEMS oscillator avoids the quartz failure mode
The base resonator is MEMS, which means the frequency is set by a silicon structure, not a quartz slab.
Operates across 1.8V to 3.3V without a separate regulator — one BOM line covers both a 1.8V core rail and a 3.3V I/O rail.
4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — fits tight-profile designs like automotive camera modules or handheld diagnostic tools. The 0.098" x 0.079" footprint is common across the DSC1001 family, so a layout change for a different frequency in the same series requires only a BOM swap, not a board spin.
No pin-compatible second source or successor is listed, but the DSC1001 family covers a wide frequency range, so a different frequency in the same package is a drop-in if the BOM position allows.
