The
The on-chip transceiver consists of a fully integrated RF front-end with modulator, and
demodulator. Base band data processing is implemented in an advanced and flexible
communication controller that enables user friendly communication via the SPI interface.

SRD solutions such as ticketing or as transceiver for telemetric applications e.g. in sensors. As
primary application, the transceiver is intended for UHF radio equipment in accordance with
the European Telecommunication Standard Institute (ETSI) specification EN 300 220-1 and the
US Federal Communications Commission (FCC) standard CFR47, part 15. The use of
accordance to FCC Par 15.247, allows for improved range in the 915 MHz band. Additionally
AX5051 is compatible with the low frequency standards of 802.15.4 (ZigBee).
The

automatically. Interrupts control the data flow between a controller and the AX5051.

600 kbps for ASK and 10 kbps to 600 kbps PSK. To achieve optimum performance for specific
data rates and modulation schemes several register settings to configure the
necessary, they are outlined in the following, for details see the
Manual.
Spreading and despreading is possible on all data rates and modulation schemes. The net
transfer rate is reduced by a factor of 15 in this case. For ZigBee either 600 or 300 kbps modes
have to be chosen.
The receiver supports multi-channel operation for all data rates and modulation schemes.
