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 Renesas' Fourth Generation FemtoClock™ NG PLL technology.

The AV9110 generates user specified clock frequencies usingan externally generated input reference, such as 14.318 MHzor 10.00 MHz crystal connected between pins 1 and 14.Alternately, a TTL input reference clock signal can be used.The output frequency is determined by a 24-bit digital wordentered through the serial port. The serial port enables the user to change the output frequency on-the-fly. The clock outputs utilize CMOS level output buffers that operate up to 130 MHz.
