Product Brief 4&.5&$)"%7"/$&%$0..6/*$"5*0/44&/4*/( 30mm XM1203F True RF™ 433/868/915 MHz Transceiver Module 55mm Industry’s Leading Low Power Wideband Transceiver General Description: Key Product Features: The XE1203F TrueRF transceiver module is a complete radio solution based on the highly integrated XE1203F integrated ISM-band radio transceiver. Designed for performance evaluation purposes, the RF module has a direct digital interface for data, RSSI output, FEI (Frequency Error Indicator) output and antenna Rx/Tx switch control. • Direct digital interface • Minimum external component count • Elimination of high-cost external components (e.g. SAW-filter) • Frequency synthesizer minimum resolution: 500Hz • Output power programmable: up to 15dBm (typ.) • High reception sensitivity: down to -114dBm (typ.) • Data rate up to 153.2 kbit/s • Low Power consumption: RX=14mA; TX=65mA @15dBm (typ.) • 11-bit Barker encoder/decoder for robust transmission in the presence of interference • Incoming data pattern recognition for receive-only with microcontroller wake up • Synchronized clock output • Bit Synchronizer (data recovery) • RSSI (Received Signal Strength Indicator) • FEI (Frequency Error Indicator) The XM1203F transceiver module enables high data rate communication at rates up to 152.3 kbit/s. The module is optimized for low power consumption in receive and standby modes. In transmit mode typical output power is +15 dBm without any external power amplifier. Three frequency ranges are available to satisfy either the European (ETSI-300 220-1) or the North American (FCC parts 15.247 and 15.249) standards. XM modules may also be ordered as part of a Starter Kit, which includes a microcontroller interface and a PCbased graphical user interface to enable range testing and more detailed product evaluation.
