AD8188/AD8189
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 V
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.
