MAX3787EVKIT

19-0395; Rev 0; 7/05 MAX3787 Evaluation Kit The MAX3787 evaluation kit (EV kit) is an assembled demonstration board that provides easy evaluation of the MAX3787 1Gbps to 12.5Gbps passive equalizer for backplanes and cables. SMA connectors with 50Ω controlled-impedance transmission lines to the MAX3787 are provided for input and output ports to facilitate connection to high-speed test equipment. ____________________Component List DESIGNATION QTY J1–J8 8 SMA connectors, edge mount, tab contact EF Johnson 142-0701-851 U1 1 MAX3787ABL 4 UCSP 1 MAX3787 EV kit circuit board, Rev A None DESCRIPTION ___________________________ Features ♦ Fully Assembled and Tested ♦ SMA Connectors for Inputs and Outputs ♦ Calibration Test Strip ♦ No Power Supply Required ______________ Ordering Information PART MAX3787EVKIT EF Johnson PHONE FAX 507-833-8822 507-833-8256 Note: Please indicate that you are using the MAX3787 when ordering from these suppliers. IC PACKAGE 4 UCSP-4 ________________________ Quick Start Caution: The MAX3787 is a DC-coupled evaluation board. Use DC-blocks when the MAX3787 is placed between test equipment and any circuit with a supplyreferenced input or output. 7 1) Set the pattern generator to 8.5Gbps with a 2 -1 PRBS pattern. Set the data output amplitude to 1Vp-p differential. 2) Connect the pattern generator data outputs to the inputs of an 18in FR4 board or 5m cable. 3) Connect the FR4 board or cable outputs to the MAX3787 EV kit inputs (IN+, IN-). 4) Connect the MAX3787 EV kit outputs (OUT+, OUT-) to an oscilloscope with 50Ω input terminations. _____________ Component Suppliers SUPPLIER TEMP RANGE -40°C to +125°C ________________________________________________________________ Maxim Integrated Products 1 For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com.
