With a supply range of 1.8V to 3.3V and CMOS output, it directly replaces quartz oscillators in most digital clock trees without changing the PCB footprint or supply rail. The MEMS resonator inherently withstands higher shock and vibration than quartz, which matters for engine-mount or chassis-mounted modules where quartz crystals can fracture or frequency-pull under acceleration. ## Power budget and standby control Maximum supply current is 7.2 mA at 40 MHz, and the standby (power-down) function drops consumption to 15 µA max — a meaningful saving for battery-backed real-time clocks or sleep-mode controllers that wake the system on a timing event. 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 — the exposed pad provides a low-inductance thermal path to the PCB ground plane, essential for maintaining frequency stability under thermal cycling.","metaTitle":"DSC1001AI5-040.0000T – Microchip MEMS Oscillator, 40 MHz","metaDescription":"Microchip DSC1001AI5-040.0000T XO (Standard) MEMS oscillator, 40 MHz, ±10 ppm stability, CMOS output, AEC-Q100, -40°C to 85°C, 1.8-3.3V.
