Output stage
The overall waveforms of the output signal are shown in
large bandwidth output amplifiers able to deliver up to 4.4 V
When a high level is applied on the BLK input (Pin 20), the three outputs are forced to “Infra Black”
level (Vib) thanks to a sample and hold circuit (described below).
The black level is the output voltage outside the blanking pulse when no video input signal is
available (see
