Three-Channel, Standard-Definition Video Filters
General Description
The MAX11501/MAX11502 integrated filters offer three
channels of 5th-order filters for standard-definition
video and include +6dB output buffers on each chan-
nel. These video filters are ideal for anti-aliasing and
DAC smoothing in applications such as set-top boxes,
security systems, digital video recorders (DVRs), DVD
players, and personal video recorders.
The MAX11501/MAX11502 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 5th-order filters provide a typical -3dB band-
width of 8.6MHz (MAX11501) and 8.9MHz (MAX11502)
and offer either a flat passband response (MAX11501)
or a +0.8dB peaking passband response (MAX11502)
on all 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 of below 1V after the back-
match resistor.
The MAX11501/MAX11502 operate from a single +5V
supply and are available in the upper commercial 0°C
to +85°C temperature range. These devices are avail-
able in small 8-pin SO packages.

MAX11501/MAX11502
Three-Channel,
Standard-Definition Video Filters
Detailed Description
Each channel of the MAX11501/MAX11502 contains a
transparent input clamp, an 8.6MHz (MAX11501) or
8.9MHz (MAX11502), 5th-order lowpass filter and an
output amplifier with a gain of two (see the Typical
Operating Circuit). The MAX11501 provides a flat pass-
band response and the MAX11502 features a +0.8dB
high-frequency boost at 5MHz on all channels to help
with system roll-off. Within the passband, each channel
amplifies the signal by two and adds 280mV of offset.
VOUT= (2 x VIN) + 0.28V
Typical voltage levels are shown in Figures 1 and 2.
Inputs
Transparent Clamps
All inputs feature transparent clamps to 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 when the
signal is AC-coupled, the internal clamp sets the sync
tip at slightly below the ground level.

Input Coupling
The choice of AC- or DC-coupling the input depends
on the video source. Many DACs provide a current out-
put and are terminated to ground with a resistor. Such
DAC outputs are conveniently DC-coupled to the
MAX11501/MAX11502. Use AC-coupling when the DC
level of the video signal is unknown or outside the
specified input range of the MAX11501/MAX11502,
such as SCART or VCCterminated DAC outputs.
DC-Coupled Inputs
If 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 Inputs
If 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 pulses (Figure 3).
For bipolar signals such as Pb and Pr, bias the AC-cou-
pled inputs to a fixed DC voltage, typically 0.59V, to ensure
that the transparent clamp remains off. A suitable network
is shown in Figure 4. Determine the bias voltage using:RVIRBCCL=+×−×()() , 21
