(2) Relation between the FC Input and Phase Characteristics
The FC bit changes the phase characteristics of the phase comparator. Both the internal charge pump output
level (D
O) and the phase comparator output (φR, φP) are reversed according to the FC bit. Also, the monitor pin
(f
OUT) output is controlled by the FC bit. The relationship between the FC bit and each of DO, φR, and φP is shown
below.
