Figure 51. Board Layout (Bottom Layer)
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 52 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 52. Cross Section of Input and Output Traces
T he board has 16 BNC type connectors: eight inputs and eight
outputs. T he connectors are arranged in two crescents around
the device. As can be seen from Figure 49, this results in all
eight input signal traces and all eight signal output traces having
the same length. T his is useful in tests such as All-Hostile
Crosstalk where the phase relationship and delay between sig-
nals needs to be maintained from input to output.
T he 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 evalu-
ation 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. Finally
a 10
μ
F capacitor should be used to decouple power supplies as
they come on to the board.
Controlling the E valuation Board from a PC
T he evaluation board include Windows-based control software
and a custom cable that connects the board’s digital interface to
the printer port of the PC. T he wiring of this cable is shown in
Figure 53. T he software requires Windows 3.1 or later to oper-
ate. T o install the software, insert the disk labeled “Disk #1 of
2” in the PC and run the file called SET UP.EX E. Additional
installation instructions will be given on-screen. Before begin-
ning installation, it is important to terminate any other Windows
applications that are running.
