Pin VIDEEM2/22KHZ (pin 13) is connected to an external de-emphasis network (for instance, 525
lines NTSC or other video de-emphasis). Alternatively, a precise 22 kHz tone may be output by I²C
bus control.
Pin S2VIDRTN (pin 8) is an external video input 1.0 V
input has a DC restoration clamp on its input. The clamp sink current is 1 µA ±15% with the input
buffer impedance greater than 1 M . This is the input signal to the Video Matrix.
Pins S1VIDOUT and S2VIDOUT (pins 5 and 6, respectively) are video drivers for SCART 1 and
SCART 2. An external emitter follower buffer is required to drive a 150-
voltage must be 1.5 V on the outputs. The video signal is 2.0 V
1.2 V sync tips. These pins receive the signals sent from the Video Matrix. The signal that will be
output from the Video Matrix is controlled by a control register. These outputs also feature High
Impedance mode for parallel connections.
Pin V12V (pin 14) is a double-bonded 12-V video power supply with ESD and guard rings.
Pin VGND (pin 16) a strategically placed double-bonded video power ground connection used to
reduce video currents getting into the rest of the circuit.
