AC-Coupled Inputs
If the input is AC-coupled, the transparent clamp will be
active and sets the sync tip or the lowest voltage of the
signal close to ground. This clamping behavior is
appropriate for unipolar signals such as Y, R, G, or B
with or without sync pulse (Figure 3).
For bipolar signals such as Pb, Pr signals, the AC-coupled
inputs should be biased to a fixed DC voltage to ensure
that the transparent clamp never turns on. A suitable
network that biases the input to typically 0.59V is shown
in Figure 4. The device has an input leakage current
(IL) of typically 0.5A and thus the bias voltage is
derived as follows:
HD Filters
The internal filters are optimized to deliver a flat pass-
band along with high stopband attenuation. The filter
characteristic has been chosen to provide an excellent
time-domain response with low overshoot. The typical
-3dB frequency of 33MHz guarantees low attenuation
in the passband, while at the same time allowing for a
typical attenuation of -48dB at 74.25MHz.
