XM1209
Ultra Low Power NFC Inductive Transceiver Module
General Description:
Key Product Features:
The XM1209 is an ultra low frequency NFC transceiver
module based on Semtech’s XE1209 single chip lowpower transceiver IC. It allows for demonstration and
evaluation of the XE1209 short-range transceiver.
• 3 Meters Communication range
• 200 µA active receiver current
• 95 µA carrier detect mode current consumption
• 150 nA sleep mode current consumption
• 70 µV sensitivity level with 200 µV carrier
detect threshold
• Optimized 36 kHz operating frequency
• DDS Transmitter for accurate data transmission
• 32.768 kHz low power reference oscillator
• 1820 bps robust FSK modulation
The XM1209 includes a separate ferrite antenna board
which is connected to the main module via an 8-pin SIL
connector. The separate interface allows for a number
of antennas to be evaluated to optimize range and
form factor for a particular application. With the ferrite
antenna supplied, the measured range is typically 2m.
XM1209 is a CMOS Ultra Low-Power transceiver for
short-range low frequency RF data communications
system. It uses 2-level Continuous Phase FSK modulation.
The receiver section includes the preamplifier, the downconverter, and the channel filters, the demodulator and
the bit synchronizer, which delivers synchronized data
at the output. The transmitter section is composed of a
Direct Digital Synthesizer (DDS), and the power amplifier
generating a square-wave output current.
Applications:
• Low data rate NFC
• BodyLAN
• Access and Security Control
• Short Range Wireless Data
The XE1209 has carrier detector to detect the presence
of a signal at the carrier frequency. The local clock
is based on a 32kHz crystal oscillator and a PLL to
generate the required Local Oscillator (LO) frequency.
