MAX9288/MAX9290 Evaluation Kit

General Description

The MAX9288/MAX9290 evaluation kit (EV kit) provides

a proven design to evaluate the MAX9288 and MAX9290

high-bandwidth gigabit multimedia serial link (GMSL)

deserializers with spread spectrum and full-duplex control

channel, with the use of a standard FAKRA coaxial cable.

The EV kit also includes Windows Vista

-, and Windows

7-compatible software that provides a simple graphical

user interface (GUI) for exercising features of the device.

The EV kit comes with a MAX9288 or MAX9290 IC

installed.

For complete GMSL evaluation, using a standard FAKRA

coaxial cable, order the MAX9288/MAX9290 coax EV kit

and a companion serializer board (e.g., the MAX9275/

MAX9279 coax EV kit referenced in this document). For

testing with STP cable, also order the MAXCOAX2STP-

HSD adapter kit. Only one adapter kit is needed per pair

of serializer and deserializer boards.

Note: In the following sections, the term serializer refers to

the MAX9275 or MAX9279 ICs and the term deserializer

refers to the MAX9288 or MAX9290 ICs. The term SerDes

refers to serializer(s) and deserializer(s).

This document applies to both coax and STP EV kits. This

document covers coax cables, but the information applies

equally to STP cables.

MAX9288/MAX9290 Evaluation Kit

Quick Start

This procedure applies to both coax and STP evaluation

kits. The coax evaluation kit is referenced here.

Required Equipment

● MAX9288/MAX9290 deserializer coax EV kit

● MAX9275/MAX9279 serializer coax EV kit

● 2m FAKRA cable assembly (included in the

MAX9288/MAX9290 coax EV kit)

● > 20MHz function generator

● Windows Vista or Windows 7 PC with a spare USB

port (direct 500mA connection required; do not use a

bus-powered hub)

● 5V DC, 500mA power supply

Note: In the following sections, software-related items are

identied by bolding. Text in bold refers to items directly

from the EV kit software. Text in bold and underlined

refers to items from the Windows operating system.

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

1) Download and install the latest version of the EV kit

software from www.maximintegrated.com.

a. Search for the MAX9288.

b. Select MAX9288 | Design Resources |

Software | MAXSerDes-N and download the

MAXSerDes-Nxxxx_Install.zip file.

c. Open the downloaded zip le and run

MAXSerDes-Nxxxx_Install.exe.

d. The installation application downloads and installs

the USB driver for the Nuvoton microcontroller. If the

USB driver installation is not successful, install the

appropriate USB driver for your computer, available at

http://www.ftdichip.com/Drivers/VCP.htm.

2) Verify that jumpers on the deserializer board are in

their default positions, as shown in Figure 12.

3) Verify that jumpers on the serializer board are in their

default positions, as shown in Figure 13.

4) Set up the system, as shown in Figure 1.

5) Power up the serializer board by connecting the

power supply to the +5VIN/GND terminals on the

serializer board.

6) Power up the deserializer board by connecting the

USB cable between the PC's USB port and

connector J10 on the deserializer board.

7) Connect the FAKRA cable from the OUT+ terminal

on the serializer board to the IN+ terminal on the

deserializer board.

8) Connect the pixel clock and function generator to the

serializer EV kit board header's H1 PCLK_IN pin.

9) Turn on the power supply and function generator.

10) Verify that LED_PWR on the serializer EV kit board

lights up, indicating that the board is powered.

11) Verify that the LOCK LED on the deserializer EV kit

board illuminates, indicating that the link has been

successfully established. If the LOCK LED is off or the

ERR LED is on, consult the Troubleshooting section

and x the problem before continuing.

12) Start the EV kit software by selecting Start | Pro-

grams | Maxim Integrated | MAXSerDesEV-N |

13) In case an operating evaluation board with a

Nuvoton microcontroller is not found, a window opens,

warning as such (Figure 2). Press OK to continue and

start the GUI anyway or press Cancel to terminate the

application. Consult the Troubleshooting section and

x the problem before continuing.

14) When an operating Nuvoton microcontroller is found,

the GUI checks the rmware version in the microcon-

troller and prompts the user to update. Press OK to

continue working, or press Cancel to stop the applica-

tions (Figure 3).

15) The Conguration Settings window appears, as

shown in Figure 4. The GUI automatically scans all

possible slave addresses and identies the

connected devices (DUTs) based on the Device IDs

read from the DUTs’ internal registers.

16) Once the Conguration Settings window is open,

press the Identify Devices button to search for

connected devices. Once the devices are identi-

ed, the corresponding conguration jumpers are

displayed to help users congure the serializer and

deserializer. Only Link Type and Device Address

selections on Conguration Setting window affect

the EV kit operation. Other items are for user refer-

ence only.

17) Press the Connect button to open the Evaluation

Kit window and the DUTs’ register maps (Figure 5).

The GUI reads all the SerDes’ internal registers and

updates the corresponding tabs.

18) Press the Read All MAX9279 button in the Serializer

group box to read all serializer registers.

19) Press the Deserializer tab and then press Read All

MAX9290 in the Deserializer group box to read all

deserializer registers.

20) Select any of the other tabs to evaluate other

functions of the SerDes.

Detailed Description of Software

To start the MAX9288/MAX9290 EV kit GUI, select Start

| Programs | Maxim Integrated | MAXSerDesEV-N |

MAXSerDesEV-N.

Conguration Settings Window

The Conguration Settings window is the rst window

that opens after successful program launch. It allows the

user to specify serializer and deserializer board setup and

mode of operation (Figure 4).

Controller Group Box

From the Controller group box, select Coax or STP

from the Link Type drop-down list, I2C or UART from

the Bus drop-down list, and click on either the Serializer

or Deserializer radio button to determine which device

should connect to the USB controller. Upon changing any

of these parameters, the selection in the jumper listing

highlights automatically, prompting the user to manually

make the corresponding jumper-position changes on the

EV kit boards.

Serializer Jumper Selection Block

The Serializer Jumper Selection block lists the jumpers

on the evaluation board of the selected Device ID and

shows the correct shunt positions based on the conditions

selected in the Controller block.

Deserializer Jumper Selection Block

The Deserializer Jumper Selection block lists the jump-

ers on the evaluation board of the selected Device ID and

shows the correct shunt positions based on the conditions

selected in the Controller block.

Figure 12 shows jumper setting on the MAX9288/

MAX9290 PCB for coax cable and I

C communication

with a USB cable connected to the deserializer board.

Refer to the MAX9288/MAX9290 IC data sheet for

detailed conguration information. See Table 1 for the

deserializer jumper settings and descriptions.

Identify Devices Button

The Identify Devices button causes the GUI to scan

the system and search for slave addresses on the bus.

Upon successful communication, it reads the Device ID

ing jumper lists on the Serializer Jumper Selection

and Deserializer Jumper Selection blocks. It is also

possible to manually select a device from the Device ID

drop-down list and manually change slave address in the

Device Address edit box. It is a good practice to utilize

the Identify Devices button and verify communication

with the DUTs before attempting to Connect.

To enable the control channel and communicate with the

serializer without applying PCLK, select Enable CLINK

Identify and then press the Connect button.

The following sections provide a brief overview of the

function buttons on the Conguration Settings window.

Connect Button

The Connect button opens up the Evaluation Kit

window. The GUI reads the SerDes registers and updates

on-screen register maps for both. Successful communica-

tion is indicated by green LED indicators. The LED indica-

tor's color glow red in case of a communication problem.

Cancel - Do No Connect Button

The Cancel - Do Not Connect button opens the

Evaluation Kit window without attempting to connect

to the microcontroller. Although there is no communi-

cation with the microcontroller, all functions and tabs

corresponding to the selected Device IDs on the

Evaluation Kit window become active once there.
