General Description

The DSA12x2/3/4 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 DSA12x2/3/4 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.
