Evaluation board description
   The wide bandwidth of the ZXFV302 4:1 channel video multiplexer necessitates some care in the layout of the printed circuit. For this reason Zetex has made available an Evaluation Board.

   The Evaluation Board layout serves as a useful example for many applications, showing a practical implementation of the advice given below.

   The ZXFV302EV can also be used to evaluate the ZXFV301 4:1 channel multiplexer. The ZXFV301 and ZXFV302 devices have very similar ac performance, with the only difference being in the active channel selection. v T g

   Figures 1, 2 and 3 show the schematic and copper layout of a double-sided printed circuit board suitable for evaluation of the device in the laboratory.
