The supply voltage accepts 1.8V to 3.3V, so the same oscillator can serve a 1.8V MCU core clock and a 3.3V peripheral bus without a separate rail regulator.
Housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — this is the standard 5x3.2mm XO footprint used across the industry, so the DSC1001BI2-033.3330 is a drop-in replacement for existing quartz-based oscillators in that form factor. Surface-mount mounting; the no-lead construction reduces parasitic inductance compared to a gull-wing package, which helps maintain signal integrity at 33.333 MHz.
