Product
General Description
The DSC12x1 family of high performance oscillators
utilizes the latest generation of silicon MEMS
technology that improves phase 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 a variety of communications,
storage, and networking applications.
The DSC12x1 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.
