HIGH SPEED DESIGN CONSIDERATIONS

The AD8188/AD8189 are extremely high speed switching

amplifiers for routing the highest resolution graphic signals.

Extra care is required in the circuit design and layout to ensure

that the full resolution of the video is realized.

First, the board should have at least one layer of a solid ground

plane. Long signal paths should be referenced to a ground plane

as controlled-impedance traces. All bypass capacitors should be

very close to the pins of the part with minimum extra circuit

length in the path. It is also helpful to have a large VCC plane on

a circuit board layer that is closely spaced to the ground plane.

This creates a low inductance interplane capacitance, which is

very helpful in supplying the fast transient currents that the part

demands during high resolution signal transitions.
