Ground connection of the power amplifier.
The RF ground return path of the power
amplifier output PAOUT (pin 14) has to be
concentrated to this pin.
RF output pin of the transmitter.
A DC path to the positive supply VS has to
be supplied by the antenna matching net-
work.
This pin is used to select the desired trans-
mitter frequency.
A logic low (FSEL < 0.5 V) applied to this pin
sets the transmitter to the 433 MHz fre-
quency range.
A logic high (FSEL open) applied to this pin
sets the transmitter to the 868 MHz fre-
quency range.
This pin is used to select the desired refer-
ence frequency.
A logic low (CSEL < 0.2 V) applied to this pin
sets the internal frequency divider to accept
a reference frequency of 6.78 MHz.
A logic high (CSEL open) applied to this pin
sets the internal frequency divider to accept
a reference frequency of 13.56 MHz.
