1 / 48 page  Rev 10 December 2008 www.semtech.com 1 XE1205 XE1205 180 MHz – 1GHz Low-Power, High Link Budget Integrated UHF Transceiver GENERAL DESCRIPTION The XE1205 is an integrated transceiver operating in the 433, 868 and 915 MHz license-free ISM (Industrial, Scientific and Medical) frequency bands; it can also address other frequency bands in the 180-1000 MHz range. Its highly integrated architecture allows for minimum external components while maintaining design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The XE1205 offers the unique advantage of narrow-band and wide-band communication, this without the need to modify the number or parameters of the external components. The XE1205 is optimized for low power consumption while offering high RF output power and channelized operation suited for both the European (ETSI EN 300- 220-1) and the North American (FCC part 15) regulatory standards. TrueRF™ technology enables a low-cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations. APPLICATIONS • Narrow-band and wide-band security systems • Voice and data over an RF link • Process and building control • Access control • Home automation • Home appliances interconnection KEY PRODUCT FEATURES • Programmable RF output power: up to +15 dBm • High Rx sensitivity: down to -121 dBm at 1.2 kbit/s, -116 dBm at 4.8 kbits. • Low power: RX=14 mA; TX = 62 mA @ 15 dBm • Can accommodate 300-1000 MHz frequency range • Wide band operation: up to 304.7 kbit/s, NRZ coding • Narrow band operation: 25 kHz channels for data rates up to 4.8 kbit/s, NRZ coding; optional transmitter pre-filtering to enable adjacent channel power below -37 dBm at 25 kHz • On-chip frequency synthesizer with minimum frequency resolution of 500 Hz • Continuous phase 2-level FSK modulation • Incoming data pattern recognition • Built-in Bit-Synchronizer for incoming data and clock synchronization and recovery • FEI (Frequency Error Indicator) with built-in AFC • RSSI (Received Signal Strength Indicator) • 16-byte FIFO for transmit / receive data buffering and transfer via SPI bus ORDERING INFORMATION Part number Temperature range Package XE1205I074TRLF(1) -40 °C to +85 °C VQFN48 (1) TR refers to tape & reel. LF refers to Lead Free package. This device is WEEE and RoHS compliant |
