TDK 5100 F
Preliminary
Wireless Components
Target Specification, July 2003
6
ASKDTA
Digital amplitude modulation can be
imparted to the Power Amplifier through this
pin.
A logic high (ASKDTA > 1.5 V or open)
enables the Power Amplifier.
A logic low (ASKDTA < 0.5 V)
disables the Power Amplifier.
7
FSKDTA
Digital frequency modulation can be
imparted to the Xtal Oscillator by this pin.
The VCO-frequency varies in accordance to
the frequency of the reference oscillator.
A logic high (FSKDTA > 1.5V or open)
sets the FSK switch to a high impedance
state.
A logic low (FSKDTA < 0.5 V)
closes the FSK switch
from FSKOUT (pin 4) to GND (pin 3).
A capacitor can be switched to the reference
crystal network this way. The Xtal Oscillator
frequency will be shifted giving the designed
FSK frequency deviation.
8
PAGND
Ground connection of the power amplifier.
The RF ground return path of the power
amplifier output PAOUT (pin 9) has to be
concentrated to this pin.
9
PAOUT
RF output pin of the transmitter.
A DC path to the positive supply VS has to
be supplied by the antenna matching net-
work.
10
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 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.
