BOARD DESCRIPTION
The four-layer evaluation boards for the AD8110/AD8111 contain
the same boards and use the same external components. The
only difference is the device itself, which offers a selection of a
gain of unity or gain of two through the analog channels. This
board has been carefully laid out and tested to demonstrate the
specified high speed performance of the device. Figure 9 shows
the schematic of the evaluation board. Figure 10 shows the
component side silkscreen. The layouts of the board’s four layers
are given in:
Component Layer—Figure 4
Signal Routing Layer—Figure 5
Power Layer—Figure 6
Bottom Layer—Figure 7

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the EVAL-AD8110EB/EVAL-AD8111EB features proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high energy electrostatic discharges.
Therefore, proper ESD precautions are recommended to avoid performance degradation or loss
of functionality.
Fully populated board with BNC-type connectors.

Package Description
Evaluation Board
Evaluation Board
EVAL-AD8110EB/EVAL-AD8111EB
Optimized for video applications, all signal inputs and outputs
are terminated with 75 W resistors. Stripline techniques are used
to achieve a characteristic impedance on the signal input and
output lines also of 75 W. Figure 1 shows a cross-section of one
of the input or output tracks along with the arrangement of the
PCB layers. It should be noted that unused regions of the four
layers are filled up with ground planes. As a result, the input
and output traces, in addition to having controlled impedances,
are well shielded.
The board has 24 BNC type connectors: 16 inputs and eight out-
puts. The connectors are arranged in a crescent around the
device. As seen in Figure 5, this results in all 16 input signal
traces and all eight signal output traces having the same length.
This is useful in tests such as All-Hostile Crosstalk where the
phase relationship and delay between signals needs to be
maintained from input to output.
