General Description
The main function of the IC is to switch 8 video input sources on 6 outputs. Each output can be switched on only
one of each input. On each input an alignment of the lowest level of the signal is made (bottom of synch. top for
CVBS or black level for RGB signals). Each nominal gain between any input and output is 6.5dB. For D2MAC or
Chroma signal the alignment is switched off by forcing, with an external resistor bridge, 5 V
DC on the input. Each
input can be used as a normal input or as a MAC or Chroma input (with external resistor bridge). All the
switching possibilities are changed through the BUS. Driving 75 load needs an external transistor. It is possible
