XE1202
433MHz / 868MHz / 915MHz
Low-power, integrated UHF transceiver
GENERAL DESCRIPTION
KEY PRODUCT FEATURES
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 RF output power: up to +15dBm
High reception sensitivity: down to –113dBm
Low power consumption: RX=14mA; TX = 48mA
@15 dBm output power
•
•
Supply voltage down to 2.7V
Wide band operation: 400kHz channels for data
rates of up to 76.8kbps, NRZ coding
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
•
Narrow band operation: down to 25kHz channels
for data rates of 4.8kbps, NRZ coding
On-chip frequency synthesizer with steps of 500Hz
Continuous phase 2-level FSK modulation
Incoming data pattern recognition
