In RXMode the crystal oscillator (XTO) together with the fractional-N PLL generates the local
oscillator (LO) signal.The RF signal coming either from the lowband input (RFIN_LB) or high-
band input (RFIN_HB) is amplified by the low noise amplifier (LNA) and downconverted by the
mixer to the intermediate frequency (IF) using the LO signal. Afterwards the IF signal is sam-
pled using a high resolution analog to digital converter (ADC). Within the RX digital signal
processing (RxDSP) the received signal from the ADC is filtered by a digital channel filter and
demodulated. Two data receive paths are included into the RxDSP after the digital channel fil-
ter. The receive path can also be configured to provide the digital output of an internal
temperature sensor (Temp( )).
