MAX9653 Evaluation Kit

Evluates:MAX9653

General Description

Features

♦ Jumper-Selectable Enable/Shutdown

♦ Single 3.3V Supply Operation

The MAX9653 evaluation kit (EV kit) is a fully assembled

and tested surface-mount PCB that contains the

MAX9653 triple-channel video-filter amplifier for high-

definition television (HDTV) applications. The filter’s

passband is typically 42MHz. The MAX9653 EV kit also

has shutdown control. The video inputs on the EV kit

are AC-coupled; the video outputs can be AC- or DC-

coupled. In addition, the MAX9653 video inputs are ter-

minated with 75Ω and the video outputs have a 75Ω

back termination resistor. The EV kit operates from a

single 3.3V DC power supply.

♦ Output Buffer with a 2V/V Gain

♦ High-Definition Television Video Filter

♦ AC-Coupled Inputs

♦ Standard 75Ω Input/Output Terminations

♦ Surface-Mount Components

♦ Fully Assembled and Tested

MAX9653 Evaluation Kit

Quick Start

Recommended Equipment

Before beginning, the following equipment is needed:

Detailed Description of Hardware

The MAX9653 EV kit is a fully assembled and tested

surface-mount PCB that contains the MAX9653 triple-

channel video-filter amplifier and buffer for HDTV appli-

cations. The MAX9653 filter has 1dB passband out to

42MHz and 50dB attenuation at 109MHz. The

MAX9653 EV kit has three input channels to accept a

full set of component video input signals.

•

3.3V DC power supply (VDD) capable of 50mA

Video signal generator (e.g., Tektronix TG-700 or

similar)

•

The appropriate video measurement equipment

(e.g., Tektronix VM5000)

The MAX9653 EV kit uses 0.1µF ceramic capacitors to

AC-couple the video input signals to the MAX9653. The

input capacitor stores a DC level such that the outputs

are clamped to the appropriate DC voltage level. All

video input terminals have a 75Ω termination to ground.

The MAX9653 EV kit video outputs can be DC- or AC-

coupled. By default, 0Ω resistors are installed on R7,

R8, R9, and C4, C7, and C8 are open; each of the

video outputs are configured to drive DC-coupled video

loads. To configure the video outputs to drive the AC-

coupled video loads, remove R7, R8, and R9, and

install the 220µF capacitors on C4, C7, and C8.

Procedure

The MAX9653 EV kit is fully assembled and tested.

Follow the steps below to verify board operation:

1) Verify that a shunt is placed on pins 1-2 of JU1 to

enable the MAX9653.

2) Connect the outputs of the video signal generator to

the Y_INPUT, PB_INPUT, and PR_INPUT BNC con-

nectors on the MAX9653 EV kit.

3) Connect the Y_OUTPUT, PB_OUTPUT, and

PR_OUTPUT BNC connectors on the EV kit to the

input of the video measurement equipment.

Shutdown Mode

The MAX9653 EV kit provides an option to configure the

MAX9653 into shutdown mode. See Table 1 for shunt

positions.

4) Connect the power-supply ground to the GND pad

on the EV kit.

5) Connect the 3.3V supply to the VDD pad on the EV kit.

Table 1. JU1 Jumper Selection

6) Set the video signal generator for the desired video

input signals.
