Product Brief 4&.5&$)"%7"/$&%$0..6/*$"5*0/4&/4*/( 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.
