The DSC1001AI2-074.2500C is an active-production MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a 74.25 MHz CMOS output — a common frequency for video and display timing in automotive infotainment and ADAS camera modules. Rated across -40°C to 85°C with ±25 ppm frequency stability, it holds timing over the full industrial and automotive cabin temperature span without the warm-up drift of a quartz crystal.
The supply voltage range of 1.8V to 3.3V lets the same oscillator serve a 1.8V core rail or a 3.3V I/O bank without a separate level translator — just tie the supply pin to the relevant rail. Active current draw is 8.7 mA max at 74.25 MHz — low enough that a standard LDO or buck regulator can feed it without a dedicated power tree branch.
Package and mounting for automated assembly
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, it fits standard pick-and-place reflow processes — no special handling beyond standard MSL bake if the moisture barrier bag is compromised. Supplied on Tape & Reel for automated assembly; the 0.90 mm profile keeps it under common 1.0 mm board-to-shield clearance limits.
