Type Description
O Composite Video. Includes synchronization, luminance
and chrominance components of video.
O Super Video Luminance. S-Video luminance signal.
O Super Video Chrominance. S-Video chrominance sig-
nal.
O TV Red. TV Red component signal for SCART.
O TV Green. TV Green component signal for SCART.
O TV Blue. TV Blue component signal for SCART.
O Intensity. Color intensity vector.
O Chrominance Red. Red axis phase angle.
O Chrominance Blue. Blue axis phase angle.
I/O Voltage Reference. Reference voltage for TV DAC. This
signal reflects the internal voltage reference. If an exter-
nal voltage reference is used, this input is tied to a
1.235V reference.
I Current Compensation for TV DAC. A 0.1 µF to 1.2 µF
capacitor is used to connect this ball to AV
I TV Set Resistor. This signal sets the current-level for the
TV DAC. Typically, an 1140 Ω, 1% resistor is connected
between this ball and AV
put of TV DACs is 32 * TVREF / TVRSET. An 1140 Ω, 1%
resistor enables driving a double terminated 75 Ω trans-
mission line.
TV Output Dump Current. Typically, a 9.3 Ω, 1% resistor
O
is connected between this ball and AV
