6.3.5 Demodulator
The receiver in the MC72000 down converts the RF signal and demodulates it. The demodulator takes the
IF signal from the limiter and delivers a baseband signal to an A/D converter (ADC). The 6-bit ADC uses
the Redundant Sign Digit (RSD) Cyclic architecture that samples the analog input at 4.0 Msamples/s. The
resulting demodulated data out of the MC72000 is a 24 Mbit/s, 2’s-complement serial bit stream. The start
of each 6-bit data stream is indicated by a frame sync (FS) signal internal to the baseband processor. A
24 MHz clock output accompanies the demodulated data.
6.3.5.1 Receiver Characteristics
For optimum intermodulation and C/I performance, the MC72000 GND_RF pins require good conduction
to the PCB ground layer. Figure 10 through Figure 16 show typical performance of the receiver for various
conditions.
