Dual MPX Usage
0.0.1 Feature Description
The TDA7406 is able to support a twin tuner concept via the Dual-MPX-Mode. The DC-
Voltage at the CMPX-pin controls whether one or both MPX-signals are used to decode the
stereo FM-signal. Therefor two window-comparators with a characteristic as shown in
Figure 19
In this mode the stereodecoder high impedance-mute mutes both inputs in parallel.
