Description
A voltage controlled, low current 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 surface mountable package is ideal for
today's automated assembly environments.
Applications
• For use in phase-locked loop (PLL)
clock and data recovery, frequency
translation, or frequency synthesis applications in video, video compression,
telephony, and LAN/WAN data communication environments.
• High and wide frequency range from
32 MHz to 125 MHz
ˆ 3.3 or 5 Volt operation
• Compact, plastic molded surface mount
package
• HCMOS and TTL compatible
• Tri-state output
• Available on tape & reel; 24mm tape,
500pcs per reel
