APPLICATION CIRCUITS
Typical application circuits are shown in Figure 8 to Figure 11. Recommended loop filters for DLRCLK and MCLKI/XTALI modes of the
PLL reference are shown in Figure 8. Output filters for the DAC outputs are shown in Figure 9 and Figure 10, and an external regulator
circuit is shown in Figure 11.
