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: PIN description and number ENABLE (pin11) CHANNEL SELECTION (pin6) TX/RX (pin12) TX DATA INPUT (pin9) Logic level 0 or open 0 or 1 0 or open 2.

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: Le caratteristiche tecniche possono subire variazioni senza preavviso.
