MAX4147 Evaluation Kit
General Description
The MAX4147 evaluation kit (EV kit) simplifies evaluation of the MAX4147 high-speed, high-output-current, differential line driver. The EV kit circuit demonstrates the MAX4147 (AV = 2V/V). This EV kit may also be used to evaluate the MAX4142. Contact the factory to order a free sample.
____________________________Features
o 300MHz Bandwidth o 2000V/µs Slew Rate o Fully Assembled and Tested
Evaluates: MAX4142/MAX4147
_________________________Quick Start
The MAX4147 EV kit is fully assembled and tested. Follow these steps to verify board operation. Do not turn on the power supply until all connections are completed. 1) Connect a +5V supply to the pad marked VCC. Connect a -5V supply to the pad marked VEE. Connect the power-supply ground to the pad marked GND. 2) Verify that there is a shunt across pins 1 and 2 of jumper JU1. 3) Apply signals to IN+ and IN-, whose differential voltage does not exceed 2.5V. These signals must not exceed the amplifier's input common-mode range of ±2.8V. 4) Connect the output marked OUT+ or OUT- to an oscilloscope through a terminated 50 cable. 5) Turn on the power supply and verify the output signal on the oscilloscope.

_______________Detailed Description
Shutdown Control
The MAX4147 provides a SHDN pin to disable the output. Table 1 lists the options available for the shutdownc o n t r o l jumper, JU1. To use an external controller, remove the shunt on JU1 completely and connect the external controller to the pad labeled SHDN. SHDN is a TTL/CMOS logic-level input.

Layout Considerations
T h e MAX4147 EV kit layout has been optimized for h i g h - s p e e d signals and low distortion, with careful attention given to grounding, power-supply bypassing, a n d signal-path layout. The small, surface-mount, ceramic bypass capacitors (C1, C2, C3, and C4) have been placed as close to the four MAX4147 supply pins a s possible. The ground plane has been removed around and under the MAX4147 to reduce stray capacitance. The removal of ground plane around the input SMA connectors reduces distortion.
