The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity versus a traditional crystal oscillator in the same 2.50mm x 2.00mm 4-SMD no-lead footprint.
Operating from 1.8V to 3.3V, this oscillator spans the common logic and SoC supply rails — no separate regulator needed if your 3.3V or 1.8V rail is already clean.
No direct pin-compatible second source is listed; the DSC1001 series is Microchip's own MEMS oscillator family. For a drop-in alternative, confirm the footprint and supply voltage match your layout.
