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 transmitter for telemetric applications e.g. in sensors. As
primary application, the transmitter 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

Spreading 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.
