Operates from a single 1.8V to 3.3V rail, covering 1.8V, 2.5V, and 3.3V logic domains without an external regulator — the same BOM entry works across multiple board variants.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator land patterns, easing a drop-in replacement evaluation.
Yes, in most designs a MEMS oscillator like the DSC1001AI2 can replace a quartz crystal + load-capacitor pair, provided the downstream IC accepts a CMOS clock input at 17.734 MHz. The ±25 ppm stability is tighter than many basic quartz oscillators, and the MEMS construction eliminates crystal aging drift and shock-related frequency shifts.
