used to sample the DATA signal without additional external signal processing. In addition, the receiver includes a
digital Received Signal Strength Indicator (RSSI), a Frequency Error Indicator (FEI) that provides information about
the local oscillator frequency error, and a pattern recognition function to detect preprogrammed sequences in the
received serial data stream. Finally, a user-selectable Barker coding/decoding feature can be activated to spread
the outgoing data with an 11-bit Barker code upon transmission and decode the incoming data upon reception by
correlating the spread data with the 11-bit Barker code.
The LNA of the receiver has two programmable operation modes: the high sensitivity mode, Mode A, for reception
of weak signals; and the high linearity mode, Modxe B, for strong signals. The operation mode is defined by the
contents of the SWParam_Rmode1 and SWParam_Rmode2 Configuration Register bits.
The demodulation chain consists of an FSK demodulator, bit synchronizer, Barker decoder and a Pattern
Recognition block. Figure 2 below illustrates the interaction between each section of the demodulation chain.
The demodulator provides a demodulated data stream from the received FSK modulated base band limited
signals, I_lim and Q_lim. If the end-user application requires direct access to the output of the demodulator, then
the RTParam_Bitsync and RTParam_Barker Configuration Register bits are set low (disabled). In this case the
