BLOCK DIAGRAM

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 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 75

Ω load 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.
