Applications
• Networking systems
• Servers and storage systems
• Profession video equipments
• Test and measurement
• FPGA/ASIC clock generation
*Extended high frequency power decoupling is recommended (see test circuit for minimum
recommendation). To ensure optimal performance, do not route RF traces beneath the
package.
