MAX3711 Evaluation Kit Evaluates: MAX3711 General Description The MAX3711 evaluation kit (EV kit) is a fully assembled and tested demonstration board that provides electrical 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.

Quick Start * MAX3711 EV kit * WindowsM PC * Oscilloscope * Pattern generator Required Equipment 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 underlined refers to items from the Windows operating system. Procedure for Initial Setup 1) Install the EV kit software on a computer by attaching 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. Windows is a registered trademark and registered service mark of Microsoft Corporation. Maxim Integrated 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 communication 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. 2 MAX3711 Evaluation Kit Evaluates: MAX3711 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 written 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.

MAX3711 EV Kit Software 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 checkbox and pressing the LOAD button. Transmitter The TRANSMITTER block allows control of the transmitter'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 Maxim Integrated 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 execute 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, individual bits are written any time a checkbox is checked or unchecked. 4 J2 ROUT- J1 ROUT+ DISABLE VCCX C3 0.01F C2 0.01F S1 DISABLE TP1 FAULT SDA_3W SCL_3W CSEL_3W TP21 SDA TP3 SCL TP2 DISABLE FAULT LOS TP22 CSEL R2 OPEN VCCD 6 5 4 3 2 1 R3 4.7k VCCX R1 4.7k TP5 LOS C1 1000pF SCL 23 21 J7 TIN+ J8 TIN- 13 14 15 16 17 C16 0.01F C17 0.01F R35 OPEN R24 100 12 TP TOUT IOUT VCCTO MDREF MDIN 18 R37 OPEN 10 19 R36 OPEN 9 11 MAX3711 U1 R4 10.0k C8 1000pF VCCX C7 0.01F 20 J4 RIN- R38 OPEN 8 22 VCCX 7 ROUT- ROUT+ CSEL DISABLE FAULT 24 C4 1000pF C6 0.01F J3 RIN+ VCCX VCCX RIN+ N.C.
