GENERAL DESCRIPTION
XE1203F BRIEF DESCRIPTION
The XE1203F is a direct conversion (Zero-IF) half-duplex data transceiver. It includes a receiver, a transmitter, a
frequency synthesizer and some service blocks. The circuit operates in the three ISM frequency ranges (434 MHz,
868MHz and 915MHz) and uses 2-level FSK modulation. In a typical application, the XE1203F is programmed by the
microcontroller through the 3-wire serial bus SI, SO, SCK to write to and read from the configuration registers.

Figure 6: XE1203 functional block diagram
The XE1203F consists of 4 main functional blocks.
The receiver converts the incoming 2-level FSK modulated signal into a synchronized bit stream. The receiver is
composed of a low-noise amplifier, down-conversion mixers, base band filters, base band amplifiers, limiters,
demodulator and bit synchronizer. The bit synchronizer transforms the data output of the demodulator into a glitch-free bit
