Operating modes
AUR.EL RTX-915 FSK FCC IC, can work in 3 different modes:
1. Power Down Mode
2. RF Transmission Mode
3. RF Reception Mode
1. Power Down Mode
By driving low level pin 11 (ENABLE) the device enters the saving-energy mode, where consumption is less
than 1uA: this mode the transceiver can’t neither receive nor transmit.
In order to guarantee low consumption, observe the following table:

Transmission mode is selected by driving to high level pin 11 (ENABLE) and 12 (TX/RX).
Driving low or high pin 9 (TX DATA INPUT) the RF carrier modulated in FSK is emitted through antenna in
the frequency selected by pin 6 CHANNEL SELECTION.
3. RF Reception Mode
Reception mode is selected by driving low pin 12 (TX/RX) and high pin 11 (ENABLE).
The data received are available at pin 10.
The change of the RF channel is permits in receive mode.
Device Usage
To take advantage of the performances detailed in the Technical Specifications, and in order to comply with
the operating conditions which characterize the Certification, the transmitter must be fitted on a printed
circuit considering the followings:
DC Supply:
1. The transceiver must be supplied by a very low voltage source, safety protected against short circuits.
Maximum voltage variations allowed: 2,3÷3,6V.
2. De-coupling, next to the transmitter, by means of a minimum 100nF ceramic capacitor.
3. Are preferable low noise linear voltage regulator circuits. Eventual voltage regulators DC-DC or AC-DC
can decrease the sensitivity level of the receiver.
Ground:
A flooded ground plane must surround the module. The circuit must be double layer, with throughout vias to
the ground planes.
Care must be taken to ensure there are no traces or ground planes under the area surrounding the antenna.
It is advise to place the antenna side module toward the edge of the host PCB or solder the module with
antenna of the edge host pcb.
The picture show the PCB design to be follow for the host circuit:

according the layout of Picture 8, with a thickness> 150um.
Assembly: the module can be assembled with automatic machine by using a suction cup tool,
applied on bigger integrated circuit
Soldering: the module can be soldered on host board, through a reflow profile for Lead-free
components.
Jedec standard “J-STD-020E”
Standard Jedec “J-STD-020E” defines temperatures and exposure times, is attached below graph
and profile table time / temperature recommended for the purpose.
For host PCB that required more reflow cycles it is recommended to solder the module at the end of
the host circuit soldering cycle, taking care to limit excessive vibrations during the terminal phase of
reflow soldering paste.
