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.
