The supply voltage accepts 1.8V to 3.3V, so a single part number can serve a 1.8V MCU clock and a 3.3V peripheral bus without a separate regulator or level translator.
The 4-SMD no-lead package (5.00×3.20 mm) matches the industry-standard 5.0×3.2 mm quartz oscillator footprint — no board layout change needed when swapping from a quartz part.
Yes, the standby (power-down) function is a listed feature. When disabled, the supply current drops to 15 µA max, allowing the oscillator to be gated off in low-power sleep modes without removing the supply rail.
A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. It offers better shock and vibration tolerance, faster startup, and typically tighter stability over temperature. The DSC1001BI2-022.8000 comes in a standard 5.0×3.2 mm 4-SMD no-lead package that is footprint-compatible with many quartz XOs of the same size — no PCB layout change is required for a direct replacement, provided the supply voltage and output type (CMOS) match.
