The DSC6003JI2B-012.0000T is a 12 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC60XXB series, delivering a CMOS output with ±25 ppm absolute pull range (APR).
The device operates across a 1.8V to 3.3V supply range, so it can be powered directly from a 1.8V MCU rail or a 3.3V system bus without an external regulator. CMOS output drives standard logic levels with a typical supply current of 1.3 mA, keeping the thermal contribution low in the 2.50 mm x 2.00 mm 4-VLGA package.

The DSC6003JI2B-012.0000T belongs to the DSC60XXB series, which shares the same package (4-VLGA) and pinout as the DSC6001 family. However, the DSC6003 includes an Enable/Disable function that the DSC6001 may lack. Verify the function pin assignment in your schematic before substituting.
Yes, this is a MEMS-based oscillator that generates a 12 MHz CMOS output directly — no external load capacitors or inverter stage needed. It is a drop-in replacement for a quartz crystal plus oscillator circuit, provided the supply voltage (1.8V–3.3V) matches your rail.
