The DSC1121AE2-041.5000 is a standard XO (Standard) MEMS oscillator from Microchip's DSC1121 series, delivering a 41.5 MHz CMOS output with ±25 ppm frequency stability across its operating range. It runs from a 2.25V to 3.6V supply rail, so it drops straight into a 3.3V or 2.5V clock tree without a separate regulator.
Any DSC1121 part with the same 6-VDFN package and enable/disable function is pin-compatible — the difference is frequency and stability grade. For example, the DSC1121AE2-025.0000 runs at 25 MHz with the same ±25 ppm stability. The supply range and footprint are identical.
