XE1205

180 MHz – 1GHz

Low-Power, High Link Budget Integrated UHF Transceiver

GENERAL DESCRIPTION

KEY PRODUCT FEATURES

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

• 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

advantage

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.

• 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
