General Description
Features
The MAX11506 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
MAX11506 IC. The MAX11506 is a six-channel video
reconstruction filter and buffer for a combination of
standard-definition television (SDTV) and high-definition
television (HDTV) applications. The filter’s passband is
typically 9MHz for SDTV and selectable between
9MHz/33MHz for SDTV/HDTV. The MAX11506 includes
o 5V Single-Supply Operation
o Output Buffer Drives One 150Ω Standard Video
Load with a +6dB Gain
o Three Fixed 5th-Order 9MHz SD Filters
o Three Selectable 6th-Order 9MHz/33MHz SD/HD
Filters
a +6dB output buffer capable of driving 2V
into a
P-P
o AC- or DC-Coupled Inputs and Outputs
o Standard 75Ω Input and Output Terminations
o Transparent Input Clamps
standard 150Ω video load.
The video input and output signals on the EV kit can be
AC- or DC-coupled. The MAX11506 video input termi-
nals are terminated at 75Ω and the output terminals are
75Ω back-terminated. The EV kit operates from a single
5V DC power supply.
o Surface-Mount Construction
o Fully Assembled and Tested
The MAX11506 EV kit can also evaluate the MAX11507
after IC replacement (U1). The EV kit is shipped with a
MAX11506 IC installed.

Detailed Description of Hardware
The MAX11506 EV kit is a fully assembled and tested
surface-mount PCB that contains a MAX11506 IC. The
MAX11506 is a six-channel video reconstruction filter
and buffer for SDTV/HDTV applications. The MAX11506
filter typically has 3dB attenuation at 9MHz for SDTV
applications and 33MHz for HDTV applications. The
device includes a +6dB output buffer capable of dri-

The MAX11506 EV kit has six input channels to accept
a full set of component video input signals. All input
and output signals on the MAX11506 EV kit can be con-
figured for AC- or DC-coupling. The EV kit’s input termi-
nals are 75Ω terminated and the video output terminals
are each back-terminated with 75Ω.
Procedure
The MAX11506 EV kit is a fully assembled and tested
surface-mount board. Follow the steps below to verify
the board operation. Caution: Do not turn on the
power supply until all connections are completed.
Jumper Selection
1) Verify that a shunt is installed across jumper JU1
(HD filter).
SD/HD Filter Select (FSEL)
The MAX11506 EV kit provides three fixed 5th-order
9MHz and three selectable 6th-order 9MHz/33MHz fil-
ters. Jumper JU1 controls the FSEL pin and% in turn% the
bandwidth of the three selectable filters (SD/HD_IN1%
SD/HD_IN2% SD/HD_IN3)% as shown in Table 1. By
default% the selectable filter bandwidth is 33MHz for an
HD video output.
2) Verify that no shunts are installed across jumpers
JU2–JU7 (AC-coupled inputs).
Evluates:6/MAX1507
3) Verify that no shunts are installed across jumpers
JU8–JU13 (AC-coupled outputs).
4) Verify that no shunts are installed across jumpers
JU14–JU19 (no DC bias input).
5) Connect the output of the video signal generator to
the SD_IN1 BNC connector on the MAX11506 EV kit.
Table 1. JU1 Jumper Selection (FSEL)
6) Connect the SD_OUT1 BNC connector on the EV kit
to the input of the video measurement equipment.

9) Set the video signal generator for the desired
video input signal. Since the input is AC-coupled
and not biased% the signal should be a unipolar
signal% such as R% G% B% or Y.
Input Coupling
The MAX11506 IC features a transparent clamp at the
video inputs that allows either AC- or DC-coupling. If the
input signal remains above ground% the transparent clamp
is inactive% offering true DC input coupling. If the signal
10) Turn on power supply and enable the video signal
generator.

drops below ground% the inputs must be AC-coupled.
The transparent clamp sets the sync tip close to ground.
DC Bias for YPbPr Signals
When configuring the EV kit video inputs for AC-coupled
operation% the correct DC bias point has to be chosen%
depending on the input signal. Unipolar signals% such as
R% G% B% and Y% are biased correctly using the
MAX11506 internal transparent clamp. For bipolar sig-
nals% such as Pb and Pr% a constant DC bias voltage has
to be applied after the AC-coupling capacitor to make
The MAX11506 EV kit provides an option to configure
the MAX11506 inputs to AC- or DC-coupling. Jumpers

ent DC bias voltage% replace resistors R16% R17% R18
and R22% R23% R24. See Table 4 for input clamp configu-
ration. Refer to the MAX11506/MAX11507 IC data sheet
