XE1202
433MHz / 868MHz / 915MHz
Low-power, integrated UHF transceiver
GENERAL DESCRIPTION
The XE1202 is a single chip transceiver operating in
the 433, 868 and 915MHz 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 XE1202 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 XE1202 is optimized
for low power consumption while offering high RF
output power and channelized operation suited for both
the European (ETSI-300-220) and the North American
(FCC part 15) regulatory standards
APPLICATIONS
• Narrow-band and wide-band security systems
• Voice and data over an RF link

• 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)

4.1.5 Transmitter
The output power of the power amplifier is programmable on four values with the register “RTParam_Tpow” (see
the Configuration register section below), as shown in the table below, where RFOPi are given in Electrical

The type of modulation of the LO frequency by the modulating bit stream is programmable through
RTParam_Filter:
- the input bit stream is directly applied to the frequency synthesizer without any pre-filtering
(RTParam_Filter=0)
- the input bit stream is pre-filtered before being applied to the frequency synthesizer; with this filtering, each
edge of the bit stream is linearly smoothed with a staircase transition (RTParam_Filter=1)
This is illustrated on the next page where DATAIN is the input bit stream to be transmitted.
