It integrates a MEMS resonator and CMOS oscillator in a single 4-SMD No Lead package measuring 2.50mm x 2.00mm, eliminating the quartz crystal and its matching network from the BOM.
The 3V supply rail is fixed — confirm the Vdd on your board matches before committing the BOM line.
Microchip lists the DSC1030DI2-027.0000T as Active.
The output is CMOS, and the supply voltage is 3V. The CMOS output is compatible with most MCU clock inputs without external level translation.
Yes, the function is Standby (Power Down). When the enable pin is pulled low, the oscillator stops and draws 1µA max. The output goes high-impedance in standby, so the downstream clock input should be pulled low or gated to prevent floating logic.
The DSC1030 family shares the same 4-SMD No Lead footprint and pinout across all frequency and stability variants. A different frequency or tighter stability grade (e.g., ±25ppm vs ±50ppm) is a direct drop-in replacement as long as the supply voltage and output type match. Confirm the frequency and stability grade against your BOM before substituting.
