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 V
C
= 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.
Plastic molded, J-lead SMD package
TTL and CMOS compatible
Tri-state output
