Xemics Debuts New XE1203 ISM Band Transceiver

Xemics (Switzerland) introduced its XE1203 ISM band transceiver that operates in the 433MHz, 868MHz and 915MHz bands, and can transmit and receive data from 1.2kbps right up to 153.2kbps. Radio frequency (RF) output can be programmed up to +15dBm and the current consumption while in reception mode is 14mA. The on-chip frequency synthesizer ensures that the chip can handle multi-channel as well as frequency hopping spread-spectrum communications.

The receiver sensitivity and transmit power enable a total link budget in excess of 128dB, enabling reliable RF links in excess of several kilometers without external amplification. The unit complies with the latest Federal Communications Commission ruling enabling transmit power up to +8dBm/3kHz without having to implement frequency hopping in the US. A special operation mode supports the European KONNEX home automation standard for RF-linked home and building automation.

An optional Barker-encoder mode improves the link robustness for low data-rate applications. The unit is available in a small VQFN package measuring 7mm x 7mm for compact RF layouts. The XE1202 is capable of operating either in a frequency-hopping, spread-spectrum mode, or as a DTS-compliant device. In an FHSS system, the fast phase-locked loop switching time of approximately 60µs translates to a direct advantage in terms of scanning available channels and synchronization.

The XE1203 is priced at $2.60 in million-piece quantities.
