TM Application Specific Crystal Oscillator 7.0 x 5.0mm 3.3V PECL Low Jitter 155.52MHz GPON XO SNGPON155 7.0 x 5.0mm Ceramic SMD ASSP XO™ for Networking Package: Product Features • Very low phase jitter - 0.5ps RMS • Thicker crystal for improved reliability • Pb-free & RoHS compliant • Industrial temperature range Recommended Land Pattern: Product Description The SN series 3.3V, 155.52MHz crystal clock oscillator achieves superb jitter for GPON applications. The output clock signal, generated internally with a patented oscillator design, is compatible with LVPECL logic levels. The device, available on tape and reel, is contained in a 7.0 x 5.0mm surface-mount ceramic package. Pin Functions: Pin Function 1 2 3 4 5 6 OE Function N/C Ground OUT OUT VCC Applications • GPON Optical Network Unit (ONU) • GPON Optical Line Termination (OLT) • GPON Gateway *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.
