The DSC6003JL3B-004.0096 is a MEMS-based XO from Microchip's DSC60XX series, delivering a 4.0096 MHz CMOS output from a 4-VLGA package. AEC-Q100 qualification (Grade 1 or 2 — the datasheet integration band determines the exact grade) means this oscillator is screened for the temperature and reliability stresses of under-hood and chassis-mounted electronics. For a BOM that already requires AEC-Q100 passives and MCUs, this part keeps the timing element on the same qualification level.
The supply range spans 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without a separate voltage regulator. At 1.3 mA typical current draw, the oscillator adds negligible load to the rail — about 4.3 mW at 3.3V, which is well below the budget of a typical automotive ECU or battery-powered sensor node.
It is available for design-in and ongoing production.
