APPLICATION CIRCUITS
Typical applications circuits are shown in Figure 21, Figure 22,
and Figure 23. Recommended loop filters for LR clock and
master clock as the PLL reference are shown in Figure 21.
Output filters for the DAC outputs are shown in Figure 22 and
Figure 23 for the noninverting and inverting cases, respectively.
