Functional Description

13 PAGND

14 PAOUT

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.

14

A DC path to the positive supply VS has to

be supplied by the antenna matching net-

work.

13

15

FSEL

VS

+1.2 V

This pin has to be shorted to ground to

select the 315 MHz transmitter frequency

range.

30 kΩ

15

A logic low (FSEL < 0.5 V) applied to this pin

sets the transmitter to the 315 MHz fre-

90 kΩ

+1.1 V quency range.

A logic high (FSEL open) applied to this pin

30 µA

sets the transmitter to the 630 MHz fre-

quency range.

16 CSEL

VS

+1.2 V

VS

This pin is used to select the desired refer-

ence frequency.

A logic high (CSEL open) applied to this pin

60 kΩ

5 µA

sets the internal frequency divider to accept

16

a reference frequency of 9.84 MHz.

60 kΩ

+0.8 V

1) Indicated voltages and currents apply for PLL Enable Mode and Transmit Mode.

In Power Down Mode, the values are zero or high-ohmic.
