XM1209

Ultra Low Power NFC Inductive Transceiver Module

General Description:

The XM1209 is an ultra low frequency NFC transceiver

module based on Semtech’s XE1209 single chip low-

power transceiver IC. It allows for demonstration and

evaluation of the XE1209 short-range transceiver.

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 down-

converter, 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.

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.
