The DSC1001CI5-024.5760 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 24.576 MHz CMOS output with ±10 ppm frequency stability.
Supply range and standby power-down
Operating from 1.7 V to 3.6 V, this oscillator spans 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator — one BOM line covers multiple supply domains. For a battery-powered ECU that sleeps between wake events, that 6.5 mA vs 15 µA difference extends standby life significantly.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it is a standard surface-mount footprint for pick-and-place. Before reflow, check the MSL — MEMS oscillators typically carry MSL 1 or 2, but confirm the label on the reel; if it is MSL 2a or above and the floor-life has been exceeded, bake it or it popcorns.
