The LA1061M counts antenna
switches for the time interval
generated by multi-vibrator 2.
The internal D/A converter
outputs a current on pin 11,
which is converted to a voltage
by the resistor connected to
this pin. If this voltage exceeds
a certain value, that is, the
switching frequency is too
high , multi-vibrator 3 operates
to hold the antenna switching
outputs at Main for the time set
by multi-vibrator 3.
