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 a variety of
communications, storage, and networking applications.
The DSC12x2/3/4 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 6-pin
LVPECL/LVDS/HCSL crystal oscillators.
