C-bus controlled YUV/RGB switch
TDA8443A
FUNCTIONAL DESCRIPTION
The circuit contains two sets of inputs (see Fig.1). Both
channels can receive RGB or YUV signals. Each set of
inputs has its own synchronization input, which internally
generates a pulse to clamp the inputs. The internal
clamping pulse can also be controlled by a signal (e.g. a
sandcastle pulse) applied to pin 24. The pulse will occur
during the time that the signal at pin 24 is between
5.5 and 6.5 V. If both a sync signal and a pin 24 signal are
used the signal should be applied to pin 24 via a 1 k
resistor.
RGB signals of Channel 2 can be matrixed to YUV signals.
The outputs can be set in a high impedance OFF state,
which allows the use of seven devices in parallel
(I
2
C-bus mode).
The circuit can be controlled by an I
2
C-bus compatible
microcontroller or directly by DC voltages. The fast
switching input can be operated via pin 16 of the
peritelevision connector.
