Four-Channel, Standard-Definition Video Filters
General DescriptionThe MAX11504/MAX11505 integrated filters offer four
channels of 5th order filters for standard-definition video
and include +6dB output buffers on each channel. These
video filters are ideal for anti-aliasing and DAC smooth-
ing in applications such as set-top boxes, security sys-
tems, digital video recorders (DVRs), DVD players, and
personal video recorders.
The MAX11504/MAX11505 video inputs feature a trans-
parent clamp compatible with AC- and DC-coupled
input signals and allow DAC outputs to be directly cou-
pled. The 5thorder filters provide a bandwidth of
8.6MHz (typical). The MAX11504 offers a flat passband
response on all channels. The MAX11505 offers a 0.8dB
peaking passband response on Channel 1, resulting in
a bandwidth of 8.9MHz (typical) and a flat passband
response on all other channels.
Each channel includes an output buffer with a gain of
+6dB capable of driving a full 2VP-P video signal into two
standard 150Ω(75Ωback terminated) video loads. The
buffers drive either AC- or DC-coupled loads and assure
a blanking level below 1V after the back-match resistor.
The MAX11504/MAX11505 operate from a single +5V
supply and are available in the 0°C to +70°C commer-
cial temperature range. These devices are available in
small 10-pin µMAX®packages.

Detailed DescriptionEach channel of the MAX11504/MAX11505 contains a
transparent input clamp, a 5th order lowpass filter, and
an output amplifier with +6dB gain (see the Functional
Diagrams and Typical Operating Circuits). The 5th order
lowpass filters provide a bandwidth of 8.6MHz (typical).
The MAX11504 provides a flat passband response. The
MAX11505 features a 0.8dB high-frequency boost on
Channel 1 to help with system rolloff (for CVBS signals)
and a flat passband response on all other channels.
Within the passband, each channel amplifies the signal
by two and adds 280mV of offset.
Typical voltage levels are shown in Figures 1 and 2.VOUTIN=×+().2028

Figure 1. Typical AC-Coupled Signal
MAX11504/MAX11505
Transparent ClampsAll inputs feature transparent clamps that allow either
AC or DC input coupling. The clamp remains inactive
while the input signal is above ground, offering true DC
input coupling. If the signal goes below ground, as
occurs when it is AC-coupled, the clamp sets the sync
tip slightly below the ground level.
Input CouplingThe choice of AC- or DC-coupling the input depends
on the video source. Many DACs provide a current
output and are terminated to ground with a resistor;
such signals are conveniently DC-coupled. Use AC-
coupling when the DC level of the video signal is
unknown or outside the specified input range of the
MAX11504/MAX11505, such as SCART or VCC-termi-
nated DAC outputs.
DC-Coupled InputsIf the input is DC-coupled, the input voltage must
remain above zero but not exceed the maximum input
voltage of 1.4V (typical).
AC-Coupled InputsIf the input is AC-coupled, the transparent clamps are
active and set the lowest point of the signal at ground.
This is appropriate for unipolar signals such as Y, R, G,
or B with or without sync pulse (Figure 3).
