I2C-bus controlled YUV/RGB switch  
TDA8443A  
I2C-bus mode  
FUNCTIONAL DESCRIPTION  
The protocol for the devices in I2C-bus mode is shown  
in Fig.3.  
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 kΩ  
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  
(I2C-bus mode).

The circuit can be controlled by an I2C-bus compatible  
microcontroller or directly by DC voltages. The fast  
switching input can be operated via pin 16 of the  
peritelevision connector.

Product specification  
I2C-bus controlled YUV/RGB switch  
TDA8443A  
When the synchronization pulse is over, the current  
source is switched off and the voltage at pin 24 will rise  
to its higher level. Because of the time constant at  
pin 24, the restoration will take some microseconds.  
The voltage at pin 24 is also sensed internally and at  
the time it is between 0.456VP and 0.544VP, a time  
pulse is generated and used for the clamping action.  
Input clamps  
The R, G, B respectively (RY), Y and (BY) video signals  
are AC-coupled to the IC where they are clamped on the  
black level. The timing information for this clamping action  
is derived from the associated synchronization signal  
SYNC, which could also consist of the composite video  
information signal CVBS. The syncsignal is AC-coupled to  
the IC where it is clamped on top-sync level, information  
obtained from this action is used to generate the clamp  
pulses.  
2. Using a sandcastle pulse (external clamping)  
If an associated sandcastle pulse is available, it can  
also be used as a clamping pulse. In this event the  
sandcastle pulse should be connected to pin 24, the  
top of the clamping pulse should be between 0.544VP  
and 0.456VP. The timing of the internal clamping pulse  
will be equal to the timing of the higher part of the  
sandcastle pulse. If the sync signal is also connected,  
the current sink will also become active during the  
synchronization pulses. This means that the  
sandcastle pulse should be connected to pin 24 via a  
1 kdropping resistor. In this event only the  
sandcastle pulse at pin 24 will be influenced during  
sync pulses, but the sandcastle pulse at the  
The clamp pulses can be generated in two ways:  
1. Using the sync information (internal clamping)  
The sync information is clamped on top-sync and the  
information obtained from this action is used to switch  
an internal current source at pin 24.  
Pin 24 should be connected to VP via a 4.7 kresistor,  
and a 1 nF capacitor to ground. During video scan the  
voltage at pin 24 will be HIGH (equals positive supply  
voltage). During the synchronization pulses the  
voltage at pin 24 will drop to zero because of the  
current sink (2.5 mA).  
sandcastle source will be unchanged.

SOLDERING  
REPAIRING SOLDERED JOINTS  
Apply a low voltage soldering iron below the seating plane  
(or not more than 2 mm above it). If its temperature is  
below 300 °C, it must not be in contact for more than 10 s;  
if between 300 and 400 °C, for not more than 5 s.  
Plastic dual in-line packages  
BY DIP OR WAVE  
The maximum permissible temperature of the solder is  
260 °C; this temperature must not be in contact with the  
joint for more than 5 s. The total contact time of successive  
solder waves must not exceed 5 s.  
The device may be mounted up to the seating plane, but  
the temperature of the plastic body must not exceed the  
specified storage maximum. If the printed-circuit board has  
been pre-heated, forced cooling may be necessary  
immediately after soldering to keep the temperature within  
the permissible limit.
