External Loop Filter

External Loop Filter Component Configuration

To implement an external loop filter, set EXLFSEL bit (6.26) high. Setting all of the control switches low that

control capacitors C1 and C2 (see Table 40) remove them from the loop filter circuit. This is necessary for an

external loop filter implementation.
