| TM Application Specific Crystal Oscillator 7.0 x 5.0mm 3.3V CMOS Low-Jitter 125MHz EPON XO FNEPON125 7.0 x 5.0mm Ceramic SMD ASSP XOTM for Networking Package: Product Features * Very low phase jitter - 0.5ps RMS * Thicker crystal for improved reliability * Low output current - 20mA max. * Low power stand by mode * Industrial Temperature Range * Pb-free & RoHS compliant Recommended Land Pattern: Product Description This is an enhanced high-frequency 3.3V, 125MHz crystal clock oscillator with superb jitter and low operating current for Ethernet Passive Optical Network (EPON) applications. The output clock signal, generated internally with a patented oscillator design, is compatible with LVCMOS logic levels. Pin Functions: Pin Function 1 2 3 4 OE Function Ground Clock Output V DD Applications * EPON Optical Network Unit (ONU) * EPON Optical Line Termination (OLT) * EPON 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.
