Low Pass Filter Input.
This terminal is biased
from the pin 6 through an
external RC filter.
Built-in ESD protective
circuit.
Low Pass Filter Output.
Built-in ESD protective
circuit.
Quick Charge/Discharge
Control.
The power supply output
voltage to pin 9 sets up the
quick charge / discharge
circuit. Instead of the power
supply, another power
source can also be used
within the limit of the rated
supply voltage. Built-in
ESD protective circuit
between pin 9 and ground.
FSK Output.
FSK comparator is a wave
shaping circuit.
A LPF output signal is
inverted and wave-shaped.
Instead of the power supply,
another power source can
also be used within the
limit of the rated supply
voltage. Built-in ESD
protective circuit between
pin 10 and ground.
Received Signal Strength
Indicator Output.
Pin 11 outputs DC level
proportional to the log of
input signal level to pin 1.
Built-in ESD protective
circuit.
