Page 5: Introduction
Introduction This is the user’s guide for the evaluation modules (EVMs) for the Texas Instru- ments’ SN65LVDS387EVM 16-channel LVDS driver EVM and the SN65LVDS386EVM 16-channel LVDS receiver EVM. One manual is used for both EVMs because the boards are similar for both devices. The EVMs are CE-compliant for distribution within the European Community. -
Page 6: The Evaluation Boards
Chapter 2 The Evaluation Boards Each EVM consists of a six-layer printed-wiring board (PWB). The LVDS device and BergStick connectors are on the top (connector side) of the board. All other passive components are installed on the underside (component side) of the PWB. A simplified input/output (I/O) block diagram of the EVM is shown in Figure 2–1. -

Vcc levels on each EVM may be evaluated. 3.4 Cables There are no cables provided with either the SN65LVDS387EVM or the SN65LVDS386EVM. When evaluating either the SN65LVDS387EVM or SN65LVDS386EVM separately, the only cables required are those connecting the input signal source to the input of the EVM. -

When connected to the test instrumentation and 3.3-Vdc power (as described in section 3), performance can be tested and observed. All I/O connections are made using standard BergSticks that allow fast and easy connections.

These EVMs has been designed to allow performance evaluation of both de- vices when connected together. This allows users to perform tests using the specific type and length of cable between the SN65LVDS387EVM and the SN65LVDS386EVM. Users also has the option to install any specific connec- tors and to use jumper wires to the BergStick connectors. -

Note: When testing an SN65LVDS387EVM and SN65LVDS386EVM together, make sure R1 through R16 (100 Ω) are not installed on the SN65LVDS387EVM. Termination of the LVDS signal lines needs to be done on the SN65LVDS386EVM. 4.4 References There is a wide selection of LVDS devices and related applications materials available to assist in the design and development of LVDS interfaces. -
