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 XE1202A TrueRF™ offers a wide range of channel bandwidths, without the need to modify the number or parameters of the external components. The XE1202A TrueRF™ is optimized for low power consumption whilst offering high RF output power and channelized operation suitable for both the European (ETSI-300-220) and the North American (FCC part 15) regulatory standards. KEY PRODUCT FEATURES Programmable RF output power: up to +15 dBm High reception sensitivity: down to –116 dBm Low power consumption: RX = 14 mA; TX = 62mA @15 dBm output power Supply voltage down to 2.4 V Data rates from 4.8 kbits/s to 76.8 kbits/s, NRZ coding Channel filter bandwidths from 20 kHz to 400 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 RSSI (Received Signal Strength Indicator) and FEI (Frequency Error Indicator) ORDERING INFORMATION APPLICATIONS Security systems Voice and data over an RF link Process and building control Access control Home automation Home appliances interconnection Part number XE1202AI027TRLF Temperature range -40 °C to +85 °C Package LQFP44 Rev 1 January 2006 VSSA VSS www.semtech.com XE1202A TrueRF™ www.DataSheet4U.com TABLE OF CONTENTS 1 Functional Block Diagram....................................................................................................................... 4 2 Pin description......................................................................................................................................... 5 3 Electrical Characteristics ........................................................................................................................ 6 3.1 Absolute Maximum Operating Ranges.................................................................................................. 6 3.2 Specifications........................................................................................................................................ 6 3.2.1 Operating Range ....................................................................................................................................... 6 3.2.2 Electrical Specifications ............................................................................................................................. 6 4 Description ............................................................................................................................................... 9 4.1 Detailed description .................................................................................................................................. 9 4.1.1 Receiver .................................................................................................................................................... 9 4.1.2 Receiver LNA modes ..........................................................................................................
