XE1203
433MHz / 868MHz / 915MHz
Low-power, integrated UHF transceiver
GENERAL DESCRIPTION
The XE1203 is a single chip transceiver operating
in the 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 XE1203 offers the unique
advantage of high data rate communication at
rates up to 152.3kbit/s, without the need to modify
the number or parameters of the external
components. The XE1203 is optimized for low
power consumption while offering high RF output
power and exceptional receiver sensitivity. The
device is suitable for circuit applications which
have to satisfy either the European (ETSI-300-
220) or the North American (FCC part 15)
regulatory standards.
APPLICATIONS
Automated Meter Reading (AMR)
Home Automation and Access Control
High-Quality Speech, Music and Data over RF
Applications requiring Konnex-compatibility
KEY PRODUCT FEATURES

500Hz
Continuous phase 2-level FSK modulation
Received data pattern recognition (for wake-
up)
Bit-Synchronizer for incoming data/clock
synchronization and recovery
RSSI (Received Signal Strength Indicator)
FEI (Frequency Error Indicator)
