This terminal is selection of
Carrier off-mode and
Antenna SW driver output.
High : Carrier ON
Low or Open : Carrier OFF
As reference signal, either
4-MHz crystal resonator can
be connected to this pin for
internal oscillation or
external signal can be input.
Reference signal Mode can
be selected pin 1.
This terminal is the
selection of RF VCO
oscillation frequency.
Open or High : USA 3ch
Low : USA 4ch
Digital GND
P / S ratio is set up by
connecting resistance with
this terminal between GND.
