Product details

The supply voltage range of 2.25V to 3.6V lets this oscillator run directly from a 2.5V or 3.3V rail without an intermediate LDO, simplifying the power tree in mixed-voltage designs.

For battery-powered systems that cycle between active and sleep states, this standby current is low enough to leave the oscillator powered continuously without draining the cell during long idle periods.

Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1101NI2-018.7500 is a surface-mount device suited for automated pick-and-place assembly. The 6-VDFN footprint requires a standard land pattern; no special via-in-pad or thermal management is needed for this low-power oscillator.

Frequently asked questions

What is the frequency of the DSC1101NI2-018.7500?

The DSC1101NI2-018.7500 outputs a 18.75 MHz CMOS clock signal.

How does the DSC1101NI2-018.7500 compare to a standard quartz crystal oscillator?

The DSC1101NI2-018.7500 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer better shock and vibration tolerance, faster startup, and smaller package options, though the frequency stability (±25 ppm) is comparable to a standard quartz oscillator.
