The 1.8V to 3.3V supply range lets it run from a single 3.3V rail or a lower-voltage core supply without an extra regulator, simplifying power distribution on mixed-voltage boards.
During active operation the part draws 6.3 mA max — low enough for a CAN transceiver reference or an Ethernet PHY clock in a 24/7 powered ECU without a thermal concern.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1001CI5-016.3840 fits into compact layouts where board real estate is at a premium — typical for automotive sensor modules or portable instrumentation. Surface-mount assembly with no leads means the package sits flush on the PCB; the small footprint leaves room for decoupling capacitors close to the supply pins, which helps maintain the ±10 ppm stability under supply ripple.
