AC couple to this input of the input buffer
amplifier.
The input buffer amplifier output.
The input to the Detect/Word filter.
The input to the VCO loop filter.
Word filter capacitor pin A.
Word filter capacitor pin B.
VCO Loop filter capacitor pin A.
VCO Loop filter capacitor pin B.
Open drain CMOS output, active on detect.
Note that a load resistor to V_SS is required.
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
recommended to prevent possible shorting to
ground.
Power supply.
