The DSC1001DL5-004.0000T: The supply voltage range of 1.8V to 3.3V allows the same part to be used across 1.8V, 2.5V, or 3.3V logic rails without a separate regulator, simplifying power tree design.
The standby pin is level-sensitive; pulling it low shuts off the output and internal bias, so the oscillator draws negligible current while the rest of the system sleeps.
The 0.098" x 0.079" land pattern is common among 2.5 x 2.0 mm oscillators, so a layout designed for a similar-sized quartz XO can often accept this MEMS part with a pad-pattern adjustment.
