Loop Filter

Figure 34 depicts the loop filter topology of the CDCE62005. It facilitates both internal and external

implementations providing optimal flexibility.

Figure 34. CDCE62005 Loop Filter Topology

Internal Loop Filter Component Configuration

Figure 34 contains five different loop filter components with programmable values: C1, C2, R2, R3, and C3.

Table 37 shows that the CDCE62005 uses one of four different types of circuit implementation (shown in

Figure 35) for each of the internal loop filter components.
