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.

Conditions

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

, T

). 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.
