DS15BR400EVK Quad LVDS Buffer/Repeater with Preemphasis Evaluation Kit User Manual August 2006 Rev 0.
DS15BR400 Evaluation Board User Manual Overview DS15BR400 is a four channel LVDS Buffer/Repeater, featuring pre-emphasis with maximum pre-emphasis gain of approximately 6 dB at 750 MHz. The device has internal 100-ohm resistors on both, the inputs and outputs, to improve performance and minimize board size. It utilizes LVDS technology for low power, high-speed and superior noise immunity.
DS15BR400 Evaluation Board User Manual All LVDS inputs and outputs are accessible through SMA connectors and suitable for connections to 50-ohm instrumentation. The power can be applied using banana plugs. The control pins, PWDN* and PEM pins, are connected to 2-position switches. Test Setup Procedure The following is a recommended test setup procedure for the device evaluation. Figure 2 depicts a typical setup and instrumentation used for the device evaluation. 1. Apply the power to the device (3.
