19.2 MHz MEMS clock source for low-voltage timing
The DSC1018DI1-019.2000 is a MEMS-based XO (Standard) from Microchip's DSC1018 series, delivering a 19.2 MHz CMOS output from a 1.8V supply rail — a common clock frequency for MCUs and SoCs in battery-powered or space-constrained designs. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — the oscillator keeps lock under the mechanical stress of portable instruments, panel-mount equipment, or engine-bay-adjacent enclosures.
Standby function and power-down current
The Standby (Power Down) function pulls the output to high-impedance and drops the supply current to 1 µA max — useful for battery-operated systems that need to gate the clock tree during sleep modes without a separate load switch. Active-mode draw is 3 mA max at 19.2 MHz, which is typical for a MEMS oscillator at this frequency and keeps the thermal contribution negligible in the 0.90 mm seated-height package.
