DESCRIPTION
The main functionof the TEA6415Cis to switch8
videoinput sourceson the 6 outputs.
Each output can be switched to only one of the
inputs whereas but any same input may be connectedto several outputs.
Alltheswitchingpossibilitiesarecontrolledthrough
2
the I
C bus.

GENERALDESCRIPTION
Themainfunctionof theICis toswitch8 videoinput
sources on 6 outputs.
Each output can be switched on only one of each
input. On each input an alignment of the lowest
level ofthesignal ismade (bottom ofsynch.top for
CVBS or blacklevel for RGBsignals).
Each nominal gain between any input and output
is 6.5dB. For D2MAC or Chroma signalthe alignment is switched off by forcing, with an external
resistor bridge,5 V
onthe input.Each inputcan
DC
be used as a normalinput or as a MAC or Chroma

input (with external resistorbridge). All the switching possibilitiesare changedthrough the BUS.
Driving 75Ω loadneeds an external transistor.
It is possible to have the same inputconnected to
severaloutputs.
The starting configuration upon power on (power
supply: 0 to 10V) is undetermined.
In this case, 6 words of 16 bits are necessary to
determineone configuration.In othercase,1 word
of 16bits isnecessary to determineone configuration.
