Anti-Alias Filter
The MAX9509 can also provide anti-alias filtering with a
buffer before an ADC, which would be present in a
NTSC/PAL video decoder, for example. Figure 5 shows
an example application circuit. An external composite
video signal is applied to VIDIN, which is terminated
with a total of 74 (56 and 18 resistors) to ground.
The signal is attenuated by four, and then AC-coupled
to IN. The normal 1VP-P video signal must be attenuat-
ed because with a 1.8V supply, the MAX9509 can only
handle a video signal of approximately 0.25VP-P at IN.
AC-couple the video signal to IN because the DC level
of an external video signal is usually not well specified,
although it is reasonable to expect that the signal is
between -2V and +2V. The 10 series resistor increas-
es the equivalent source resistance to approximately
25, which is the minimum necessary for a video
source to drive the internal sync-tip clamp.
For external video signals larger than 1VP-P, operate
the MAX9509 from a 2.5V supply so that IN can accom-
modate a 0.325VP-P video signal, which is equivalent to
a 1.3VP-P video signal at VIDIN.
