XE1209

The

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. The XE1209 has a simple interface with

an external microcontroller.
