MAX9517/MAX9524 Evaluation Kits
Evluate:17/MAX9524
General Description
Features
♦ Single 2.7V to 3.6V Supply Operation
♦ DC-Coupled Input (MAX9517)
The MAX9517/MAX9524 evaluation kits (EV kits) are
fully assembled and tested surface-mount PCBs that
evaluate the MAX9517 and the MAX9524 ICs. Both ICs
filter, amplify, and set the sync-tip level for standard-
definition video signals.
♦ AC-Coupled Input with Sync-Tip Clamp
(MAX9524)
The ICs feature an internal reconstruction filter that has
40dB attenuation at 27MHz, and 1dB passband flat-
ness at 7MHz. The MAX9517 and MAX9524 have a
2V/V gain and are capable of driving 75Ω to ground.
The ICs feature two analog switches that are used to
route audio, video, or digital signals.

1dB Passband at 7MHz Reconstruction Filter
with 40dB Attenuation at 27MHz
♦ Preset Gain of 2V/V
♦ Drives 75Ω to Ground
♦ Small 12-Pin Thin QFN Package
♦ Fully Assembled and Tested
Video signals are DC-coupled to the input of the
MAX9517 and AC-coupled to the input of the MAX9524.
The MAX9524 features an input sync-tip clamp to set
the DC level for the video signal. The EV kits’ input ter-
minal has 75Ω termination to ground. The EV kits’ out-
put has a 75Ω back-termination resistor. The EV kits
operate from a single 2.7V to 3.6V power supply.

Detailed Description
Each EV kit is a fully assembled and tested PCB that
contains all the components necessary to evaluate the
performance of the MAX9517 or the MAX9524. Both ICs
filter and amplify standard-definition video signals.

The MAX9517/MAX9524 ICs feature an internal recon-
struction filter that has 40dB attenuation at 27MHz and
1dB passband flatness at 7MHz. The MAX9517 and
MAX9524 have 2V/V gain and are capable of driving a
75Ω load to ground. Both ICs include two analog
switches that can be used to route audio, video, or digi-
tal signals.
Note: Indicate that you are using the MAX9517 or MAX9524
when contacting these component suppliers.
Quick Start
Recommended Equipment
• 2.7V to 3.6V, 500mA DC power supply (VDD)
The MAX9517 EV kit can be modified to evaluate the
MAX9524 by installing capacitor C3, removing resistor
R3, and replacing U1. See the EV-Kit Specific
Component List for component values.
• Video signal generator
• Video measurement equipment (e.g., Tektronix VM-
700T)
Similarly, the MAX9524 EV kit can be modified to evalu-
ate the MAX9517 by removing capacitor C3, installing
resistor R3, and replacing U1. See the EV-Kit Specific
Component List for component values.
Procedure
Each EV kit is a fully assembled and tested surface-
mount PCB. Follow the steps below to verify 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 pins 1-2 of
Shutdown Mode (SHDN)
Jumper JU1 controls the shutdown mode (SHDN) of the
MAX9517 or MAX9524 ICs. The shutdown mode
reduces the IC’s quiescent current. See Table 1 for
shunt positions.
jumper JU1 (EV Kit ON).
2) Connect the power-supply ground to the GND pad
on the EV kit.
3) Connect the 2.7V to 3.6V power supply to the VDD
pad on the EV kit.

Table 1. JU1 Jumper Selection (SHDN)
4) Connect the output of the video signal generator to
the IN BNC connector on the EV kit. Note: For the
MAX9517, the video signal must be biased such that
the sync tip is at ground.

5) Connect the OUT BNC connector on the EV kit to the
input of the video measurement equipment.
*Default position.
6) Set the video signal generator for the desired video
input signal, such as multiburst sweep. This signal
must contain sync information.
7) Turn on the power supply and enable the video sig-
nal generator.
8) Analyze the video output signal with the VM-700T
video measurement equipment.

switch 1. Jumper JU2 on the EV kit controls analog
switch 1. Table 2 lists the selectable jumper options.
Analog Switch Control (IN2)
The ICs feature a logic input, IN2, to control analog
switch 2. Jumper JU3 on the EV kit controls analog
switch 2. Table 3 lists the selectable jumper options.
