Video Source with a Positive DC Bias
In some applications, the video source generates a sig-
nal with a positive DC voltage bias,
i.e., the sync tip of
the signal is well above ground. Figure 6 shows an
example in which the outputs of the luma (Y) DAC and
the chroma (C) DAC are connected together. Since the
DACs are current mode, the output currents sum togeth-
er into the resistor, which converts the resulting current
into a voltage representing a composite video signal.
If the chroma DAC has an independent output resistor
to ground, then the chroma signal, which is a carrier at
3.58MHz for NTSC or at 4.43MHz for PAL, has a posi-
tive DC bias to keep the signal above ground at all
times. If the luma DAC has an independent output
resistor to ground, then the luma signal usually does
not have a positive DC bias, and the sync tip is at
approximately ground. When the chroma and luma sig-
nals are added together, the resulting composite video
signal still has a positive DC bias. Therefore, the signal
must be AC-coupled into the MAX9516 because the
composite video signal is above the nominal, DC-cou-
pled 0V to 0.25V input range.
Video Signal Routing
Minimize the length of the PCB trace between the out-
put of the video DAC and the input of the MAX9516 to
reduce coupling of external noise into the video signal.
If possible, shield the PCB trace.
