FemtoClock® NG Crystal-to- 3.3V,2.5V LVPECL Clock Generator W/Fanout Buffer

The 8V89704I is a four output Clock Generator with LVPECL outputs. The 8V89704I can generate any one of four frequencies from a single crystal or reference clock. The four frequencies are selected from the Function Table (Table 3) 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 IDT's Fourth Generation FemtoClock® NG PLL technology.
