FG Schmitt output
Power supply
Insert a capacitor between this pin and ground
to prevent noise from entering the IC. (Use a
value of 20 or 30 µF or higher.)
Phase lock detection output
Turns on (goes low) when phase lock is
detected.
Start/stop control
Low: 0 to 1.5 V
High: 3.5 V to VREG
Hysteresis: About 0.5 V
Apply a low level to start; this pin goes high
when open.
Clock input
Low: 0 to 1.5 V
High: 3.5 V to VREG
Hysteresis: About 0.5 V
fCLK = 10 kHz maximum
If there is noise on the clock signal, remove
that noise with a capacitor.
Stabilized power supply output (5 V output)
Insert a capacitor between this pin and
ground for stabilization. (About 0.1 µF.)
