GENERAL DESCRIPTION
The main functionof 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 align-
ment is switched off by forcing, with an external
resistor bridge, 5 VDC 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 switch-
ing possibilities are changed through the BUS.
Driving 75load needs an external transistor.
It is possible to have the same input connected to
several outputs.
The starting configuration upon power on (power
supply : 0 to 10V) is undetermined.
In this case, 6 words of 16 bits are necessary to
determine one configuration. In other case, 1 word
of 16 bits is necessary to determine one configura-
tion.
