Ground connection for FSK modulation out-
put FSKOUT.
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 has to be left open to select the
915 MHz transmitter frequency range.
A logic low (FSEL < 0.5 V) applied to this pin
sets the transmitter to the 457 MHz fre-
quency range.
A logic high (FSEL open) applied to this pin
sets the transmitter to the 915 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 7.15 MHz.
A logic high (CSEL open) applied to this pin
sets the internal frequency divider to accept
a reference frequency of 14.3 MHz.
