LMH730277

The LMH730277 evaluation board is designed to aid in the characterization of National Semiconductor's High Speed 2:1 Multiplexers. Use the evaluation board as a guide for high frequency layout and as a tool to aid in device testing and characterization. The evaluation board schematic is shown in PDF. Refer to the product data sheets for recommendations for component values.

Here are some technical specifications about the LMH730277: (1)Use a ground plane; (2)Include large (6.8 F) capacitors on both supplies (C3 & C4); (3)Near the device use .01 F ceramic capacitors from both supplies to ground (C1, C2); (4)A capacitor between V+ and V- is optional (C5) but will help suppress second order harmonic distortion; (5)Remove the ground and power planes from under and around the part, especially near the OUT and FB pins; (6)Minimize all trace lengths; (7)Use terminated transmission lines for long traces.
