Figure 6 shows the state diagram for phase comparator 2.
Each circle represents a state of the comparator. The
number at the top, inside each circle, represents the state
of the comparator, while the logic state of the signal and
comparator inputs are represented by a ‘0’ for a logic LOW
or a ‘1’ for a logic HIGH, and they are shown in the left and
right bottom of each circle.
The transitions from one to another result from either a
logic change at the signal input (S) or the comparator input
(C). A positive-going and a negative-going transition are
shown by an arrow pointing up or down respectively.
The state diagram assumes, that only one transition on
either the signal input or comparator input occurs at any
instant. States 3, 5, 9 and 11 represent the condition at the
output when the p-type driver is ON, while states 2, 4, 10
and 12 determine the condition when the n-type driver is
ON. States 1, 6, 7 and 8 represent the condition when the
output is in its high impedance OFF state; i.e. both p and
n-type drivers are OFF, and the PCP
OUT
output is HIGH.
The condition at output PCP
OUT
for all other states is LOW.
