NOTES
1. Currents shown are for the transceiver only.
2. Peak input current requirements are>100mA as the 100μF capacitor has to be charged
3. V
may be supplied from an external source, in which case V
CC

should not be connected. See AN142
for further information.

Table 3 Channel allocation
Illegal Channel Allocation
In order to keep transmissions to within the 2·4 to 2·5GHz
frequency band, channels 101 and above will default to the
channels within this band as listed in Table 4.
Note that the channels used are dependent on the frequency
allocation in the country of use and the drive circuit/control logic
must limit the selected channels to within these frequency limits.
Antenna Ports
Two antenna ports are available (ANT1 and ANT2) for
receiver diversity and are selected by ANTSEL (pin 5 on the
40-way connector).These ports have 50
V
nominal impedance.
The port isolation is specified in Table 1.
TRANSCEIVER CHARACTERISTICS
General Electrical Performance
DC power supply requirements
The V
CC
(
1
5V) power supply needs to be well regulated,
low noise (less than 20mVp-p ripple and noise) and have a
source impedance of less than 50m
V
at 1kHz. The V
CC
supply
has been separated from the input (V
CC
5
) to the
2
5V (V
EE
)
generator to provide greater flexibility in the overall system
design.
Extra care should be taken with ripple and noise
suppression of the V
CC
supply if the V
supply is connected
to the radio’s main V
CC
supply. If supplied separately, ripple and
noise on the V
CC
2
5
supply should be less than 100mVp-p
at 1kHz.
NOTE: Ripple and noise on the
1
5V power supply (V
)
modulates the transmitter output and levels above those speci-
fied will result in increased spurious output from the DE6003,
and will also cause degradation in receiver sensitivity.

Stresses above those listed may cause permanent damage
to the transceiver. These are stress ratings only and functional
operation of the transceiver at those conditions, or at any other
condition above those indicated in the operation section of this
data sheet is not implied. Exposure to Absolute Maximum
Rating conditions for extended periods may affect device
reliability.
NOTE: The V

supply must be applied not less than
10ms before the V
supply. Failure to observe this require-
ment could result in premature failure of the transceiver.
