XE1203
433MHz / 868MHz / 915MHz
Low-power, integrated UHF transceiver
KEY PRODUCT FEATURES
GENERAL DESCRIPTION
• RF output power: up to +15dBm on a 50 Ω
load (typical)
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.
• High reception sensitivity: down to –113 dBm
(typical)
• Low power consumption:
RX = 14mA; TX = 62 mA @15dBm (typical)
• Supply voltage down to 2.4V
• Data rate from 1.2 to 152.3kbps, NRZ coding
• Konnex-compatible operation mode
• 11-bit Barker encoder/decoder
• On-chip frequency synthesizer with steps of
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)
APPLICATIONS
• Automated Meter Reading (AMR)
ORDERING INFORMATION
• Home Automation and Access Control
• High-Quality Speech, Music and Data over RF
• Applications requiring Konnex-compatibility
