The DSC1001AI1-033.0000 is a 33 MHz standard XO (Standard) oscillator built on a MEMS resonator, delivering a CMOS output across a 1.8V to 3.3V supply range.
That ratio means a battery-powered module that sleeps most of the time — a wireless sensor node or a parked-vehicle ECU — keeps the oscillator off when not needed, extending battery life without a separate load switch.
Housed in a 4-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Standard reflow profiles for 1.6 mm-thick boards work; no special bake-out required unless the parts have been exposed to humidity beyond MSL level 3.
