Supply voltage spans 1.8V to 3.3V, letting it run directly from a 1.8V core rail or a 3.3V I/O rail without an external regulator. Supplied in Tape & Reel (TR) packaging, the 4-SMD no-lead footprint (3.20 mm x 2.50 mm, 0.90 mm seated height) is a standard 4-pin oscillator layout compatible with common pick-and-place and reflow profiles. ## MEMS vs. quartz — drop-in with different startup This is a MEMS-based oscillator, not a quartz crystal. It generates the 12.5 MHz clock internally from a silicon MEMS resonator and CMOS driver — no external load capacitors or crystal needed. The CMOS output is a direct replacement for a quartz oscillator module of the same frequency and output type, but the MEMS startup time is typically faster (sub-millisecond) and the part is more resistant to vibration and shock than a quartz resonator.","metaTitle":"DSC1001CE1-012.5000T Microchip MEMS Oscillator 12.5 MHz","metaDescription":"Microchip DSC1001CE1-012.5000T MEMS XO, 12.5 MHz, CMOS output, ±50 ppm stability, 1.8V-3.3V supply, AEC-Q100 qualified.
