Description

A voltage controlled crystal oscillator

providing precise rise and fall times to

drive high performance applications. The

device is packaged in a 6-pin, SMD, J

leaded package. The plastic molded sur-

face mountable package is ideal for to-

day's automated assembly environments.

±50 ppm over all conditions: operating temperature, voltage change,

load change, calibration tolerance, aging, with VC = 2.5V

Applications

•

For use with phase-locked loop (PLL)

for clock and data recovery, frequency

translation, or frequency synthesis ap-

plications in video, telephony, and data

communication environments.
