MAX3987 Evaluation Kit
The MAX3987 evaluation kit (EV kit) is a fully assembled
and tested PCB that demonstrates the capabilities of the
MAX3987 8.5Gbps quad equalizer and preemphasis
driver. The EV kit can be controlled using a PC to run
the evaluation software or using DIP switches mounted
on the EV kit to bias hardware pins. The included software is WindowsM compatible and provides a simple
graphical user interface (GUI) to configure all available
device features. The software communicates with the EV
kit through a USB port and provides three methods for
configuration. The primary method is a simple point-andclick interface. The other debug interfaces allow direct
register read/write operations, or software-controlled
external pin programming. The data I/O traces on the
EV kit are controlled impedance with matched lengths.
All external connections are AC-coupled with standard
SMA connectors for easy connection to test equipment.

*EP = Exposed pad.
Quick Start
The MAX3987 evaluation kit (EV kit) is designed to operate in a stand-alone pin-bias hardware-controlled mode
or a software-controlled mode requiring the use of a PC
and software. In the pin-bias hardware-controlled mode,
the EV kit uses DIP switches SW1 and SW2 on the EV kit
board to configure the MAX3987. If additional control is
desired, a GUI software interface is provided to control
the individual registers, allowing per-channel setting of
items such as signal preemphasis and output amplitude
levels.

2) Set the SW2-1 switch labeled I2C_EN to the ON position to enable pin-bias mode. Note that in this mode the
DIP switch settings control all 4 channels. To control the
channels individually, software mode must be used.
1) Install a shunt on jumper JP_ between 5V-ADAPTER
and BOARD_POWER to use an external 5V wall
adapter.
3) Using the information in Tables 1, 2, and 3, set the
remaining SW1 and SW2 DIP switches to configure
the device for the desired mode of operation.

3) Click Next to accept the default destination folder.
See Figure 4.
Evaluation Software Installation
Installing the evaluation software for the EV kit on a PC
has one or two steps. The first step involves running the
EV kit software installer. The second step involves installing the USB driver, and is only necessary when the driver
is not already installed on the PC.
Note: Do not connect the USB port of the EV kit to the
PC until the MAX3987 Evaluation Kit Setup Wizard has
successfully completed the software installation.
1) Run the MAX3987_REV#.#.msi installer package that
was supplied with the EV kit.
2) Click Next at the welcome screen dialog box. See
Figure 3.
Figure 4. Software Installer Destination Folder Selection
4) Click Next to begin the software installation. See

3) Click Browse my computer for driver software to
begin the driver installation. See Figure 11.
USB Driver Installation
(Windows Vista and Windows 7)
When the USB port of the EV kit is connected to a PC
with Windows Vista or Windows 7, Windows does not
automatically install the driver nor does it start the Found
New Hardware Wizard. It is necessary to manually install
the USB driver using the Windows Device Manager.
1) Open the Windows Device Manager. To do this,
use the following path in Windows: Start→Control
Panel→System and Security→System→Device
Manager.
2) In the Device Manager window, there is a section labeled Other devices with a device labeled
Unknown device. Right-click on the Unknown
device followed by Update Driver Software. See
Figure 10.
Figure 11. Update Driver Software—Manual Install
4) Click the Browse button and select the same installation directory used in step 3 of the GUI software installation instructions (the default directory is
C:\Program Files\MAX3987 Evaluation Kit). Click Next
to continue. The Found New Hardware Wizard
searches for a short duration before continuing with
the driver installation. See Figure 12.

Additional Information
External Processor Control
The EV kit is intended to be controlled using the on-board
microcontroller in conjunction with a PC running the EV
kit evaluation software. However, the EV kit provides
additional jumper points that can be used to connect the
device’s I2C bus to an external processor. By connecting EV kit pins J5.1 and J5.3 to the I2C bus of an external
processor, it is possible to fully interact with the device.
For more information, refer to the MAX3987 IC data sheet
at www.maxim-ic.com/MAX3987.
