描述

The 8T49N008I is an eight output Clock Generator with selectable LVDS or LVPECL outputs. The 8T49N008I can generate any one of four frequencies from a single crystal or reference clock. The four frequencies are selected from the Frequency Selection Table (Table 3) and are programmed via I2C interface. The four predefined frequencies are selected in the user application by two frequency selection pins. Note the desired programmed frequencies must be used with the corresponding crystal as indicated in Table 3. Excellent phase noise performance is maintained with Renesas' 4TH Generation FemtoClock™ NG PLL technology, which delivers sub-0.5ps RMS phase jitter.
