General Description
The DSA12x1 family of high performance oscillators
utilizes the latest generation of silicon MEMS
technology that reduces close-in noise and provides
excellent jitter and stability over a wide range of supply
voltages and temperatures. By eliminating the need for
quartz or SAW technology, MEMS oscillators
significantly enhance reliability and accelerate product
development,
while
meeting
stringent
clock
performance criteria for automotive applications.
The DSA12x1 family features a control function on pin
1 or pin 2 that permits either a standby feature
(complete power down when STDBY is low), output
enable (output is tri-stated with OE low), or a frequency
select (choice of two frequencies selected by FS
high/low). See the
Product Identification System
section for detailed information.
All oscillators are available in industry-standard
packages, including the small 2.5 mm x 2.0 mm, and
are “drop-in” replacements for standard 4-pin and 6-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

,
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.
