General Description of Operation
The ZULU Transceiver Module provides a highly integrated ‘plug and play’ Radio solution.
Based on the Silicon Labs1013 Chipset, the Zulu Transceiver integrates a high power RF
Transmitter (+20dBm) with high sensitivity receiver (-121dBm), and 8051microcontroller, and
a DC-DC converter enabling ultra lower battery operation to 0.9V
For detail operation of the device please see Silicon Labs Datasheet.

Description
RF22 peripheral interrupt status pin. Will be set low to
indicate a pending RF22 interrupt event. See the RF22
Control Logic Registers for more details. This pin is an
open-drain output with a 220k internal pull-up resistor.
An external pull-up resistor is recommended.
A Out
AO RF22 peripheral crystal oscillator output. Connect to
an external 30 MHz crystal or leave floating if driving the
XIN pin with an external signal source.
A in
RF22 peripheral crystal oscillator input. Connect to an
external 30 MHz crystal or to an external source. If using an external clock source with no crystal, dc coupling
with a nominal 0.8 VDC level is recommended with a
minimum ac amplitude of 700 mVpp.

Mechanical Dimensions
Range
The antenna choice and position directly controls the system range. Keep it clear of other
metal in the system. The best position by far, is protruding vertically from the top of the product. This is often not desirable for practical reasons and thus a compromise may be needed.
Note that the space around the antenna is as important as the antenna itself. All radio systems are dependant on a radio signal being received through airspace.
The range quoted is the optimal in direct line of sight without obstacles and in good atmospheric conditions.
Range is affected by many things, for example local environmental conditions, atmospheric
conditions, interference from other radio transmitters. For evaluating the local environment
please see our RF Meter (DS006)
In very worse case applications the range quoted may be reduced below 30% of the optimal
range stated.
Recommended Miniature Antenna 868MHz
The BEAD Antenna provides a Miniature PCB mounting solution
where a high performance is required from a small space .
Available as straight or 90 degree mount this antenna is a general
purpose omni-directional. Please see Datasheet ANT-BEAD-868
