I need to multiplex five AD8148 video driver in order to make a video network.

i saw in the specs that we can do it by using the OPD (Output Pull Down ) feature in ordrer to present a high

impedance at the output. But the condition is to use serials schottky diodes.


Is there any schematic for this particular use, and what about the bias of theses diodes ?


In the spec it is mentionned that we can use VOCM but the AD8148 does't have one.



thanks for your help .
