• Manufacturer Part Number: XE1203
• Description: Low-Power, integrated UHF transceiver
• Manufacturer: ETC1 [List of Unclassifed Manufacturers]

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.
