Microchip DSC1121NI2-025.0000 is a 25 MHz MEMS-based XO (Standard) with CMOS output, ±25 ppm frequency stability, and a 2.25V–3.6V supply range — one BOM entry covers 2.5V, 3.0V, and 3.3V rails without a separate regulator.
The 6-SMD no-lead footprint is the same 7.00mm x 5.00mm as standard quartz oscillators, so the PCB layout does not change.
Yes — the 6-SMD no-lead package and 7.00mm x 5.00mm footprint match standard quartz oscillator dimensions. The MEMS resonator provides faster startup and better vibration tolerance, but the electrical interface (CMOS output, same supply range) is identical.
