Ultra Low Jitter PLL Crystal Oscillator 2.5 x 2.0mm NX24SB 2.5V/3.3V HCSL FS XO 2.5 x 2.0mm Ceramic SMD Package: (Scale: none, Dimensions are in mm) Product Features Recommended Land Pattern: • 4 selectable output frequencies 2.70 • Meet PCIe Gen2 and Gen3 clock requirements at 100MHz 1.50 0.70 0.60 1.11 • Low supply current - 70mA max. 0.57 2.25 • Thicker crystal for improved reliability 0.35 • Wide frequency range - 5 ~ 212.5MHz 0.95 • Very low phase jitter - < 1.0ps RMS max. • Industrial Temperature Range Pin Functions: • Pb-free & RoHS compliant • Fast lead time Pin Product Description The NX24SB XO series is a high performance HCSL crystal oscillator family with very low jitter performance. Depending on customers' needs, this family devices can support 4 different frequencies using the FS select pins. It supports various options including wider frequency range, 2.5V/3.3V voltage, and various stabilities. It is designed to meet the clock source specifications for communication systems, and other high performance equipment. *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.
