TDA9852
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 Zo and the composite input
impedance (see Chapter “Characteristics”, Section “Input level adjustment control”) must be taken into account.
2. In order to prevent clipping at over-modulation
(maximum deviation in the BTSC system for 100% modulation is 73 kHz).
3. For example colour bar or flat field white; 100% video modulation.
