Anti-Alias Filter
The MAX9507 can also provide anti-alias filtering with a
buffer before an analog-to-digital converter (ADC),
which would be present in an NTSC/PAL video decoder,
for example. Figure 18 shows the application circuit. An
external composite video signal is applied to VIDIN,
which is terminated with a total of 74
Ω (56Ω and 18Ω
resistors) to ground. The signal is attenuated by four,
and then AC-coupled to IN. The normal 1VP-P video sig-
nal must be attenuated because with a 1.8V supply, the
MAX9507 can only handle a video signal of approxi-
mately 0.25VP-P at IN. AC-couple the video signal to IN
because the DC level of an external video signal is usu-
ally not well specified, although it is reasonable to
expect that the signal is between -2V and +2V. The 10
Ω
series resistor increases the equivalent source resis-
tance to about 25
Ω, which is the minimum necessary for
a video source to drive the internal sync-tip clamp.
For external video signals larger than 1VP-P, then oper-
ate the MAX9507 from a 2.5V supply so that IN can
accommodate a 0.325VP-P video signal, which is equiv-
alent to a 1.3VP-P video signal at VIDIN.
