General Description
The DSC61xx family of MEMS oscillators combines the
industry leading low power consumption and
ultra-small packages with exceptional frequency
stability and jitter performance over temperature. The
single-output DSC61xx 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. They also meet the stringent mechanical
durability and reliability requirements within Automotive
Electronics Council standard Q100 (AEC-Q100), so
they are well suited for under-hood applications as well.
The DSC61xx family is available in ultra-small
1.6 mm x 1.2 mm and 2.0 mm x 1.6 mm packages.
Other package sizes include: 2.5 mm x 2.0 mm and
3.2 mm x 2.5 mm. These packages are “drop-in”
replacements for standard 4-pin CMOS quartz crystal
oscillators.

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., T
A
, T
J
,
θ
JA
). Exceeding the max-
imum allowable power dissipation will cause the device operating junction temperature to exceed the max-
imum +150°C rating. Sustained junction temperatures above +150°C can impact the device reliability.
