Maximum input level
Figure 47. CCIR330 video line
TSH7x
The input level must not exceed the following values:
• Negative peak: must be greater than -VCC+400 mV
• Positive peak value: must be lower than +VCC-400 mV
The electrical characteristics show the influence of the load on this parameter.

Video capabilities
To characterize the differential phase and differential gain, a CCIR330 video line is used.
The video line contains five (flat) levels of luma on which is superimposed a chroma signal.
The first level contains no luma. The luma gives various amplitudes which define the
saturation of the signal. The chrominance gives various phases which define the color of the
signal.
Differential phase (respectively differential gain) distortion is present if a signal chrominance
phase (gain) is affected by luminance level. They represent the ability to uniformly process
the high frequency information at all luminance levels.
When differential gain is present, color saturation is not correctly reproduced.
The input generator is the Rohde and Schwarz CCVS. The output measurement was made
by the Rohde and Schwarz VSA.
