Clock Scheme
When TDA7500A is used in AD/FM mode the following scheme is choosen in order to avoid harmonics inside
the FM band. Parts of the system are directly clocked by the crystal oscillator, whereas other parts are driven
by the pll oscillator. Thanks to this it is possible to process any audio source as well analog as digital in parallel
to record FM mono for traffic informations, telephone resp. navigation and RDS. Figure 21 shows the clock
scheme. Regarding on the country and its FM bandwidth different crystals should be selected.
