XE1202A TrueRF™

433 MHz / 868 MHz / 915 MHz

Low-Power, Integrated UHF Transceiver

GENERAL DESCRIPTION

KEY PRODUCT FEATURES

The XE1202A TrueRF™ is a single chip transceiver

operating in the 433, 868 and 915 MHz license free

ISM (Industry Scientific and Medical) frequency

bands. 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.

Programmable RF output power: up to +15 dBm

High reception sensitivity: down to –116 dBm

Low power consumption: RX

TX = 62mA @15 dBm output power

Supply voltage down to 2.4 V

14 mA;

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)
