Function

1

PDWN

Disable pin for the complete transmitter cir-

cuit.

A logic low (PDWN < 0.7 V) turns off all

transmitter functions.

A logic high (PDWN > 1.5 V) gives access to

all transmitter functions.

PDWN input will be pulled up by 40 µA inter-

nally by setting DATA to a logic high-state.

2

VS

This pin is the positive supply of the trans-

mitter electronics.

An RF bypass capacitor should be con-

nected directly to this pin and returned to

GND (pin 3) as short as possible.

3

GND

General ground connection.

4

LF

Output of the charge pump and input of the

VCO control voltage.

The loop bandwidth of the PLL is 150 kHz

when only the internal loop filter is used.

The loop bandwidth may be reduced by

applying an external RC network referencing

to the positive supply VS (pin 2).
