Quick Start

Recommended Equipment

• 2.7V to 3.6V, 500mA DC power supply (VDD)

• Video signal generator

• Video measurement equipment (e.g., Tektronix VM-

700T)

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.

1) Verify that a shunt is installed across pins 1-2 of

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.

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.

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.

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.

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.

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.

Jumper Selection

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.
