Pin No.
Pin name
Function
Equivalent curcuit
22
PD
Phase comparator output pin.
The phase error is converted to a pulse duty and output from
this pin.
22
VREG
300
23
CLD
Phase lock signal mask time setting pin.
A mask time of about 90ms can be set by inserting a
capacitor (about 0.1
F) between this pin and ground. Leave
this pin open if there is no need to mask.
23
VREG
300
24
FGS
FG Schmitt output pin.
Open collector output.
24
VREG
25
LD
Phase lock detection output pin.
Open collector output.
Turns on (goes low) when phase lock is detected.
25
VREG
26
S/S
Start/stop control pin.
Low: 0 to 1.5V
High: 3.5V to VREG
Hysteresis: About 0.5V
Apply a low level to start; this pin goes high when open.
26
VREG
22k
2k
27
CLK
Clock input pin.
Low: 0 to 1.5V
High: 3.5V to VREG
Hysteresis: About 0.5 V
fCLK = 10kHz maximum
If there is noise on the clock signal, remove that noise with a
capacitor.

VREG
22k
2k
30
VCC
Power supply pin
Insert a capacitor between this pin and ground to prevent
noise from entering the IC. (Use a value of 20 or 30
F or
higher.)
