Sound VCO oscillation
frequency is compared with
4.5MHz, and the error is
outputted by Charge pump.
LPF for high frequency
rejection is connected to
this terminal. And the
voltage for sound VCO
control is generated.
The reference frequency is
20.8 kHz.
Analog Vcc
This terminal is a driver
output for an Antenna SW
switching and controlled by
the terminal 6.
The maximum output
current is 15mA.
RF signal output pin.
Low-impedance
emitter-follower output
