The MEMS resonator construction gives it inherent shock and vibration tolerance compared to quartz-based oscillators, which is relevant for automotive and industrial environments where mechanical stress is a concern. ## Supply voltage and logic compatibility The supply voltage range spans 1.7V to 3.6V, covering 2.5V and 3.3V logic rails directly — no external regulator needed for the oscillator supply. CMOS output is compatible with standard digital logic families (LVCMOS, 3.3V CMOS, 2.5V CMOS) without level translation, simplifying the clock tree. Standby (Power Down) function reduces current draw to 15 µA max when the oscillator is disabled, useful for power-sensitive designs that gate the clock during sleep modes. ## Package footprint and layout considerations Housed in a 4-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm max, the DSC1001AI1-125.0000 has a standard surface-mount footprint that matches many quartz XO packages in the same form factor. The exposed pad provides a low-thermal-resistance path to the PCB ground plane; for best thermal and electrical performance, the pad should be soldered to a copper land with thermal vias, as recommended in the datasheet layout guidelines. Sourced through independent distribution channels; quoted to order against the BOM quantity.","metaTitle":"DSC1001AI1-125.0000 Microchip MEMS XO, 125 MHz, AEC-Q100","metaDescription":"Microchip DSC1001AI1-125.0000: MEMS-based XO, 125 MHz CMOS output, AEC-Q100 qualified, 1.7V-3.6V supply, -40°C to 85°C.
