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.

4.1.7 Pattern recognition block
This feature can be activated by setting RTParam_Pattern to high while in receiver mode. The incoming NRZ bit
stream is compared with a pattern stored in PATParam_Pattern registers. The PATTERN output is driven by the
output of this comparator and is synchronized by DCLK. It is set to high when a matching condition is detected,
otherwise set to low. PATTERN output is updated at the rising edge of DCLK. The number of bits used for
comparison is defined in ADParam_Psize register and the number of tolerated errors for the pattern recognition is
defined in ADParam_Ptol register. The next figure shows the pattern matching operation.
