Programmable FemtoClock™ NG LVPECL/LVDS Clock Generator with 6-Outputs

The 8T49N006I is a six output Clock Generator with selectable LVDS or LVPECL outputs. The 8T49N006I 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 1) 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 or clock frequency as indicated in Table 1. Excellent phase noise performance is maintained with Renesas’ Fourth Generation FemtoClock™ NG PLL technology, which delivers sub-400fs RMS phase jitter.
