The wide supply voltage range of 1.8V to 3.3V lets it sit on a shared 1.8V MCU rail or a 3.3V peripheral bus without an intermediate regulator, simplifying the power tree.
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 — a standard footprint that matches many quartz XO packages, so a board layout designed for a 7x5 mm quartz can often accept this MEMS part without a pad revision.
No. As a MEMS oscillator with a CMOS output, the DSC1001AI2-024.0000T generates a rail-to-rail digital clock signal internally — it does not need the external load capacitors that a quartz crystal resonator would require. The output drives a standard CMOS load directly.
The standby (power down) function disables the oscillator output and reduces the supply current to 15 µA max. The part resumes normal oscillation when the standby pin is de-asserted; the startup time is typical for MEMS oscillators (microseconds, not milliseconds).
MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. They offer faster startup, better resistance to vibration and shock, and typically maintain ±25 ppm stability without the aging drift of quartz. The DSC1001 series uses a MEMS base resonator with a CMOS driver.
