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 (
φ
R,
φ
P) 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 D
O
,
φ
R, and
φ
P is shown below.
