Input Stages
The device offers several input stages for the different signals which have to be handled by
the system. A quasi differential input (see
The two mono differential inputs allow the connection of phone & navigation (see
or it could be used as fully differential stereo input. Additionally a single-ended stereo input
is available for Cassette applications. The lower part of the input section is dedicated to the
tuner signals. Another quasi differential input (see
referred to the tuner reference (Tuner). This concept supports also double tuner systems.
Also two seperate level inputs are present which are followed by level-shifters to allow the
use of the TDA7500's ADCs. For AM noise blanking an envelope detector driven by the AM
IF is also available.
