DSA2311KA2-R0005VAO

Crystal-less™ Configurable Clock Generator

for Automotive

General Description

DSA2311KA2-R0005VAO is a crystal-less clock

generator

that

is

factory

configurable

to

simultaneously output two separate frequencies

from 2.3 to 170MHz.

The clock generator uses proven silicon MEMS

technology to provide low jitter and high frequency

stability across a wide range of supply voltages and

temperatures. By eliminating the external quartz

crystal, crystal-less clock generators significantly

enhance

reliability

and

accelerate

product

development,

while

meeting

stringent

clock

performance criteria for a variety of

consumer

electronics, communications, and storage applications.

DSA2311KA2-R0005VAO

has

an

output

enable/disable feature allowing it to disable the

outputs when OE is low. The device is available in a

space-saving 6-pin 2.5mm x 2.0mm TDFN package

that needs only a single external bypass capacitor.

Features
