Product Description
The NX254 XO series is a high performance
HCSL crystal oscillator family with very low
jitter performance. Other than PCIe clock
frequencies, it also supports various options
including other Networking frequencies,
2.5V/3.3V voltage, and various stabilities.
It is designed to meet the clock source
specifications for PCIe interface, SGMII of
communication systems, and other high
performance equipment.
Applications
• Networking systems
• Servers and storage systems
• Profession video equipments
• Test and measurement
• FPGA/ASIC clock generation
