Ultra Low Jitter HCSL Crystal Oscillator 5.0 x 3.2mm NX504 2.5/3.3V HCSL XO 5.0 x 3.2mm Ceramic SMD Package: (Scale: none, Dimensions are in mm) Product Features Recommended Land Pattern: • Meet PCIe Gen2 and Gen3 clock requirements at 100MHz • Very low phase jitter - < 1.0ps RMS max. • Wide frequency range - 5 ~ 212.5MHz • Thicker crystal for improved reliability • Low supply current - 70mA max. • Industrial Temperature Range CREATED USING CADSTD LITE FREEWARE FROM WWW.CADSTD.COM. NON-COMMERCIAL USE ONLY. • Pb-free & RoHS compliant • Fast lead time Pin Functions: Product Description The NX504 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. Pin Function 1 OE Function 2 N/C 3 Ground 4 Q 5 Q 6 VCC *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. Part Ordering Information: Applications CREATED USING CADSTD LITE FREEWARE FROM WWW.CADSTD.COM. NON-COMMERCIAL USE ONLY.
