General Description
The DSC60xxB family of MEMS oscillators combines
industry-leading low-power consumption, ultra-small
packages with exceptional frequency stability, and jitter
performance over temperature. The single-output
DSC60xxB MEMS oscillators are excellent choices for
use as clock references in small, battery-powered
devices such as wearable and Internet of Things (IoT)
devices in which small size, low power consumption,
and long-term reliability are paramount. The
Automotive Grade AEC-Q100 qualified option is
available for this device.
The DSC60xxB family is available in ultra-small
1.6 mm x 1.2 mm, 2.0 mm x 1.6 mm and 2.5 mm x
2.0 mm packages. These packages are “drop-in”
replacements for standard 4-pin CMOS quartz crystal
oscillators.
