AC couple to this input. Nominal input
impedance is 200 kΩ.
Nominal output impedance is 1 kΩ.
Detect filter resistor pin.
PLL loop filter resistor pin. For improved
performance C4 may be chosen to provide 30°
of phase shift at the loop filter input.
Detect filter capacitor pin A
Detect filter capacitor pin B
Loop filter capacitor pin A
Loop filter capacitor pin B
PMOS open drain output - active on detect.
Ground.
Bandwidth control resistor pin A
Bandwidth control resistor pin B
VCO capacitor B
VCO capacitor A
VCO discharge resistor. When potentiometer
tuning is required, a series resistor is
recommend to prevent possible shorting to
ground.
Power supply.
