Supply voltage spans 1.7V to 3.6V, letting it run from a 1.8V or 3.3V rail without a separate regulator, and the standby (power-down) function drops supply current to 15 µA max — useful for battery-backed modules that need to stop the clock when idle.
Package, footprint, and supply routing
Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1003BI1-040.0000 fits standard oscillator footprints and reflow profiles for surface-mount assembly. The 1.7V–3.6V wide supply range simplifies rail selection — a single 3.3V or 1.8V plane powers the oscillator, and the 7.4 mA max supply current keeps the thermal load low enough that no dedicated copper pour is needed under the package.
