The DSC1001DL5-019.2000: AEC-Q100 qualification means this oscillator is rated for automotive environments — engine bay, cabin, or chassis domains — where temperature cycling and vibration are routine. The 1.8V to 3.3V supply range lets a single BOM line serve multiple voltage rails without a translator, simplifying inventory for multi-voltage designs.
Enable/Disable function and low-power standby
Active current draw is 6.3 mA max at 19.2 MHz, keeping the thermal contribution low in the compact 2.50 mm x 2.00 mm 4-SMD no-lead package.
