MAX9513 Evaluation Kit
General Description
The MAX9513 evaluation kit (EV kit) is a fully assembled
and tested surface-mount printed circuit board (PCB)
that contains a MAX9513 IC. The MAX9513 is a video
filter amplifier with SmartSleep and bidirectional video
support for standard-definition television (SDTV) appli-
cations. The filter’s passband is 6.75MHz. The two
amplifiers each have +6dB gain and can drive a 2V
P-P
video signal into two DC-coupled 150Ω loads to ground
or one AC-coupled 150Ω load.
The MAX9513 EV kit can be configured to select
between two sets of input signals: internal or external.
The EV kit provides a connector that supports bidirec-
tional video signals. A sync-tip clamped input is also
available for processing external signals.
The MAX9513 includes a SmartSleep feature that
reduces the supply current when no video input signal
is detected or when an output load is removed.
The EV kit has two video input signals, one DC-coupled
and one AC-coupled. The video output signals from the
EV kit can be DC- or AC-coupled. The MAX9513 video
input terminals have a 75Ω termination resistor to
ground and the output terminals have a 75Ω back ter-
mination resistor. The EV kit operates from a single 2.7V
to 3.6VDC power supply.

Quick Start
Recommended Equipment
•
•
•
2.7V to 3.6V, 500mA DC power supply (VDD)
Video signal generator
Video measurement equipment (e.g., Tektronix
VM700T or equivalent)
The MAX9513 EV kit can be configured to select
between two sets of input signals: internal or external.
When the internal video signal is selected, the
MAX9513 filters and amplifies the input video signal at
INTERNAL_CVBS. The EV kit outputs the video signal
at the CVBS_OUT1A, CVBS_OUT1B, CVBS_OUT2A,
and CVBS_OUT2B BNC connectors.
When the external video signal is selected, the
MAX9513 clamps and amplifies the input video signal at
EXTERNAL_CVBS (JU4 set to 1-2) or CVBS_OUT1B
(bidirectional through capacitor C5, if present, and JU4
set to 2-3). The EV kit outputs the video signal at the
CVBS_OUT2A and CVBS_OUT2B BNC connectors.
CVBS_OUT1 is internally connected to ground through a
low-impedance switch when the external video mode is
selected, thereby converting the 75Ω back termination
resistor into an input termination resistor.
The MAX9513 includes a SmartSleep feature that
reduces the supply current when no video input signal
is detected, or when an output load is removed.
SmartSleep only works in the internal mode and with
DC-coupled loads.
The MAX9513 filter’s passband is 6.75MHz. The
MAX9513’s internal amplifiers each have +6dB gain and
can drive a 2V
P-P
video signal into two DC-coupled
150Ω loads to ground, or one AC-coupled 150Ω load.
The INTERNAL_CVBS input signal line is DC-coupled
and the EXTERNAL_CVBS input signal line is AC-cou-
pled. The output signals from the EV kit can be either
DC- or AC-coupled. To AC-couple the outputs, remove
the shorts across C5 and C6 and install 220µF capaci-
tors at C5 and C6. Note that AC-coupling will introduce
line-time and field-time distortion to the video output
signal. The MAX9513 video input terminals have a 75Ω
termination resistor to ground and the output terminals
have a 75Ω back termination resistor.
Procedure
The MAX9513 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed:
1) Verify that a shunt is installed across pins 1-2 of
jumper JU1 (EV kit on).
2) Verify that a shunt is installed across pins 2-3 of
jumper JU2 (SmartSleep disabled).
3) Verify that a shunt is installed across pins 2-3 of
jumper JU3 (internal video selected).
4) The setting of jumper JU4 is ignored when internal
video is selected.
5) Connect the output of the video signal generator to the
INTERNAL_CVBS BNC connector on the MAX9513
EV kit. The video signal must be biased so that the
sync tip is at ground. A luma or composite video sig-
nal can be applied to the INTERNAL_CVBS BNC.
6) Connect the CVBS_OUT1A BNC connector on the EV
kit to the input of the video measurement equipment.
7) Connect the power-supply ground to the GND pad
on the EV kit.
8) Connect the 2.7V to 3.6VDC power supply to the
VDD pad on the EV kit.
9) Set the video signal generator for the desired video
input signal and verify that the sync tip is at ground.
10) Turn on the power supply and enable the video sig-
nal generator.
11) Analyze the video output signal with the video mea-
surement equipment.
Jumper Selection
Shutdown Mode (
SHDN
)
Jumper JU1 controls the shutdown pin (SHDN) of the
MAX9513 IC. See Table 1 for shunt positions.
Detailed Description
The MAX9513 EV kit is a fully assembled and tested
surface-mount PCB that contains a MAX9513 IC. The
MAX9513 IC has a video reconstruction filter, a 2:1
mux, and two video amplifiers for SDTV applications.
These filters and amplifiers process composite video
signals with blanking and sync (CVBS).

video signal to be processed. Two external video sig-
nals can be connected to the MAX9513 EV kit: one at
the EXTERNAL_CVBS BNC and the other at the
CVBS_OUT1B BNC connector. See Table 4 for shunt
