MAX3711 Evaluation Kit
Evaluates: MAX3711
General Description
The MAX3711 evaluation kit (EV kit) is a fully assembled
and tested demonstration board that provides electri-
cal and optical evaluation of the MAX3711, which is
a 125Mbps to 3.125Gbps integrated limiting amplifier
with a dual-loop laser driver. The controlling software
communicates with the EV kit through the USB port of
the included card and provides simplified control of all
functions of the device. The EV kit can be fully powered
by the USB port or the user can choose to power the
device with an external 3.3V supply while the USB port
supplies the included HFRD-46-1 USB daughter card.
The laser connection on the evaluation board allows
attachment of lasers in TOSA packages.

• WindowsM PC
• Oscilloscope
• Pattern generator
Note: In the following sections, software-related items
are identified by bolding. Text in bold refers to items
directly from the EV kit software. Text in bold and under-
lined refers to items from the Windows operating system.
Procedure for Initial Setup
1) Install the EV kit software on a computer by attach-
ing the USB daughter card to the computer using
the supplied USB cable. After the USB device
has been detected and installed by the operating
system, a flash drive becomes available in the
Devices with Removable Storage section of My
Computer. Search the flash drive for the MAX3711
EV kit.zip file. Copy this file to the desktop or another
known folder and unzip the file. Locate the newly
created MAX3711 EV kit folder and run setup.exe.
2) After installation is complete, follow this path to
start the program: Start | All Programs | Maxim
Integrated Products | MAX3711 EV Kit GUI. The
software is a graphical user interface (GUI) meant to
simplify control of the device.
3) Insert the USB daughter card (HFRD-46-1) into
connector J14 on the EV kit.
4) Set the jumper on JU26 to the desired power-supply
option (USB or external supply).
5) If an external power supply is used, set the voltage
to 3.3V, the current limit to 300mA, and connect the
supply to the board.
6) Connect the computer to the USB daughter card with
a USB cable (A-male to mini-B-male). Several LEDs
should illuminate, indicating that the USB source is
powered. Press the Initialize button in the software
to initiate communication to the EV kit. When commu-
nication is established, the STATUS indicator on the
GUI turns green.
Procedure for Transmitter Evaluation
1) Solder a laser to connection D5. See Figure 1 for
more information about the laser connection.
2) Connect a 50I source to TIN+ and TIN- (J7 and J8).
Set the source differential amplitude to 500mVP-P.
Set the source common-mode voltage to 2V or use
external DC blocks.

3) Connect the output from the TOSA to an optical
receiver (either an optical-to-electrical converter or
an optical input head on an oscilloscope).
4) All controls of the device are available in the
software. Fault and warning indicators are displayed
on the right side of the GUI window. When a hard fault
has occurred, the part goes into latched shutdown.
The source of the fault should be removed and the
DISABLE box should be toggled to reset the part.
5) The registers contain a default setting and can be
read using the Block Read All button. For detailed
register functions, refer to the MAX3711 IC data
sheet.
6) Note that the GUI software automatically sets the
device into “setup mode” before writing to a register.
If the Enable Block Write checkbox is checked,
multiple writes can be buffered by the GUI and writ-
ten all at once when the TX Block Write or Block
Write All button is clicked.
Procedure for Receiver Evaluation
1) Connect a 50I source to RIN+ and RIN- (J3 and J4).
2) Connect outputs ROUT+ and ROUT- (J1 and J2) to
50I oscilloscope inputs.
3) The receiver controls are located in the RECEIVER
section of the GUI.
4) Note that the GUI software automatically sets the
device into “setup mode” before writing to a register.
If the Enable Block Write checkbox is checked,
multiple writes can be buffered by the GUI and
written all at once when the RX Block Write or Block
Write All button is clicked.

Detailed Description of Software
Graphical User Interface (GUI)
The GUI consists of four main sections: RECEIVER,
TRANSMITTER, DUAL POWER CONTROL, and Block
Read and Write.
Receiver
All the controls for the receiver portion of the device are
included in the RECEIVER block. The SET_CML and
SET_LOS registers are written to by inserting the desired
decimal value for the register in the appropriate check-
box and pressing the LOAD button.
Transmitter
The TRANSMITTER block allows control of the transmit-
ter’s general settings. Pressing the TX Read button reads
all the registers shown in the transmitter section.
Dual Power Control
The DUAL POWER CONTROL block allows adjustment
and monitoring of the transmitter’s dual power-control
loops. A sub-block in this section (DATA REPORTING)
uses the device’s registers to calculate the apparent
average power (NAPC), the apparent extinction ratio (IR),
and the average MD current (IMDAVG). The MD0REG
and MD1REG values shown in the GUI are 16 bit and
range from 0 to 255 in steps of 0.0039.
Block Read and Write
The Block Read and Write section allows the user to
read/write to more than one register at a time. Pressing
any of the Block Read buttons causes the GUI to exe-
cute a block read of the appropriate group of registers.
By checking the Enable Block Write checkbox, the user
is able to change multiple registers without a write being
executed each time. The GUI buffers the commands
and executes them in a single write command once
the appropriate Block Write button has been pressed.
Note that if a Block Write button is not pressed, indi-
vidual bits are written any time a checkbox is checked
or unchecked.
