The DSC1001DI5-030.0000T is a 30 MHz MEMS-based XO with CMOS output, built for environments where a quartz crystal's vibration sensitivity or start-up time is a concern. The MEMS resonator is sealed at the die level, so the oscillator survives the shock and temperature cycling typical of engine-bay or factory-floor electronics. That puts it in the same reliability class as the rest of the automotive bill — no separate screening needed for under-hood or cabin modules.
Supply range and power-down budget
The supply voltage covers 1.8V to 3.3V, so it runs from a 1.8V core rail or a 3.3V I/O rail without an extra regulator. Maximum draw is 7.2 mA — low enough that a 100 mA LDO can feed the oscillator plus a handful of logic loads. That matters for battery-backed modules that need the clock stopped during sleep and a fast wake-up — the MEMS resonator starts in under 5 ms, which is faster than a quartz crystal's start-up.
Package and storage for the reel
4-SMD, No Lead package, 2.50 mm x 2.00 mm body, 0.90 mm seated height. The footprint matches the standard 2.5 x 2.0 mm oscillator land pattern — no via-in-pad needed, and the small size leaves room for decoupling caps near the supply pins. Supplied on Tape & Reel; store the reels in a dry cabinet if the ambient humidity exceeds 60% RH — the MEMS die itself is hermetic, but the solder pads can oxidize.
