Low Pass Filter Input
An external RC components
forms a band pass filter between
pin12 and pin13.
This terminal is biased from pin 11
though an external RC filter.
Low Pass Filter Output
Quick Charge / Discharge
Control
The power supply output voltage
to pin 14 sets up the quick charge
/ discharge circuit.
Instead of V+, another power
source can also be used within
the limit of the rated supply
voltage.
FSK Output
The FSK comparator is a wave
shaping circuit. A Filter Amplifier
output signal is inverted and wave
shaped. Instead of V+, another
power source can also be used
within the limit of the rated supply
voltage.
Carrier Sense Output
This pin outputs the result of RSSI
comparator by comparing RSSI
output level with an external input
level to pin 18.
