Figure 52. Evaluation Board-PC Connection Cable
Optimized for video applications, all signal inputs and outputs
are terminated with 75
resistors. Stripline techniques are used
to achieve a characteristic impedance on the signal input and
output lines, also of 75
. Figure 51 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.

Figure 51. Cross Section of Input and Output Traces
The board has 32 BNC type connectors: 16 inputs and 16
outputs. The connectors are arranged in a crescent around the
device. As can be seen from Figure 47, this results in all 16
input signal traces and all 16 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.
The three power supply pins AVCC, DVCC and AVEE should
be connected to good quality, low noise,
±
5 V supplies. Where
the same
±
5 V power supplies are used for analog and digital,
separate cables should be run for the power supply to the
evaluation board’s analog and digital power supply pins.
As a general rule, each power supply pin (or group of adjacent
power supply pins) should be locally decoupled with a 0.01
μ
F
capacitor. If there is a space constraint, it is more important to
decouple analog power supply pins before digital power supply
pins. A 0.1
μ
F capacitor, located reasonably close to the pins,
can be used to decouple a number of power supply pins. Fi-
nally a 10
μ
F capacitor should be used to decouple power sup-
plies as they come onto the board.
