Product Description
Pin Functions:
The NX324 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.

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.
