25 MHz MEMS oscillator — industrial-grade timing
Frequency stability is ±25 ppm — tight enough for a 25 MHz MCU clock tree without needing a TCXO; the 6 mA max supply current keeps the thermal contribution low in a compact 2.5 mm × 2.0 mm 4-SMD package.
The 1.7 V minimum supply means the oscillator continues running during a brown-out condition on a 1.8 V rail, avoiding a clock reset when the supply dips.
The DSC1003 series is Microchip's standard MEMS oscillator family; the base product number DSC1003 confirms this is a current catalog item, not a legacy or sunset line.
