Figure 50. Cross Section of Input and Output Traces
T he board has 24 BNC type connectors: 16 inputs and 8 out-
puts. T he 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 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 signals 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 adja-
cent 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 rea-
sonably 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 soft-
ware 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 51. T he software requires Win-
dows 3.1 or later to operate. 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 beginning installation, it is
important to terminate any other Windows applications that
are running.
When you launch the crosspoint control software, you will
be asked to select the printer port you are using. Most
modern PCs have only one printer port, usually called
LPT 1. However some laptop computers use the PRN port.
