General Description

The IDT8V89704I is a four output Clock Generator with LVPECL

outputs. The IDT8V89704I 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.
