Data Sheet

XE1203

The XE1203 is a single-chip integrated circuit solution intended for use as a low cost FSK transceiver to establish a

frequency-agile, half-duplex, bi-directional RF link, with NRZ (non-return to zero) data coding. Barker

encoder/decoder hardware can be activated to modulate/demodulate the transmitted signal to reduce the effects of

fixed-frequency in-band interference. The device is available in a VQFN48 package and is designed to provide a

fully functional multi-channel FSK transceiver. It is intended for applications in the 868MHz European band and the

North American 902-928MHz ISM band. The single chip transceiver operates down to 2.4 V and provides low

power consumption solutions for battery-operated and power sensitive applications. The XE1203 is capable of

operating data rates as high as 152.3 kbit/s. This makes it ideally suited for applications where high data rates are

required.
