315 MHz ASK/FSK Transmitter in 10-pin Package

Infineon Technologies 

TDK5111F

Functional Description

Pin Symbol

No.

8 PAGND

9 PAOUT

10 PDWN

Interface Schematic

Function

Ground connection of the power

amplifier.

9 The RF ground return path of the

power amplifier output PAOUT

(pin 9) has to be concentrated to

this pin.

RF output pin of the transmitter.

8 A DC path to the positive supply

VS has to be supplied by the

antenna matching network.

Disable pin for the complete

VS

transmitter circuit.

40 µA ∗ (ASKDTA+FSKDTA) A logic low (PDWN < 0.7 V) turns

off all transmitter functions.

5 kΩ

10

A logic high (PDWN > 1.5 V) gives

"ON" access to all transmitter functions.

150 kΩ

250 kΩ

PDWN input will be pulled up by

40 µA internally by either setting

FSKDTA or ASKDTA to a logic

high-state.

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

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