Applications
• Networking systems
*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.
• Servers and storage systems
• Profession video equipments
• Test and measurement
• FPGA/ASIC clock generation

Notes:
1. Stability includes all combinations of operating temperature, load changes, rated input (supply) voltage changes, initial calibration tolerance (25°C),
aging (1 year at 25°C average effective ambient temperature), shock and vibration.
2. Phase jitter typical value is depending on output frequencies.
3. For specifications other than those listed, please contact sales.
