TDA9855
Requirements for the composite input signal to ensure correct system performance
Notes
1.
Low-ohmic preferred, otherwise the signal loss and spreading at COMP, caused by Z
o
and the composite input
impedance (see Chapter “Characteristics”, Section INPUT LEVEL ADJUSTMENT CONTROL) must be taken into
account.
In order to prevent clipping at over-modulation (maximum deviation in the BTSC system for 100% modulation is
73 kHz).
