1. An Overview
PCI-Proto LAB/PLX-S is an efficient aid for developing add-on boards for personal com-
puters and other computer systems which are equipped with a PCI bus.
This board makes a quick and uncomplicated test of newly developed electronic circuits on
the PCI bus possible.
PCI-Proto LAB/PLX-S works with the universal PCI Target Controller PCI9030 from PLX
Technology, Inc., which controls typical PCI operation modes and complies with the PCI Lo-
cal Bus Specification Revision 2.2.
The board is assembled, tested and ready for immediate operation. The system designer can
mount his own hardware directly on the user area and start with the tests. This means that you
can minimize dealing with the signal plays and the technical properties (timing etc.) of the
PCI bus system.
PCI-Proto LAB/PLX-S is a long PCI board manufactured in four layers. It can be trans-
formed into a short board when cutting it off at the marked place.
PCI-Proto LAB/PLX-S
is designed as a universal board that supports either 3.3V or 5V PCI
bus operation.
It's operating voltage for all electronic circuits is 3.3V.
PCI-Proto LAB/PLX-S
will work at
older PCI slots with 5V only, if a Low Drop voltage regulator for 3.3V main supply is
mounted at the board. The user can set /reset (depending on the board) special solder jumpers
to archive his board supply from 5V or 3.3V at the used PCI slot.
The connection for 3.3V and ground is made through each of its own layers. For the 5V sup-
ply there is a grid structure on the component side.
PCI-Proto LAB/PLX-S is delivered with premounted bracket. The user may retro-equip it
with a 15-pin sub-D connector and a BNC connector.
We have added to PCI-Proto LAB/PLX-S's hardware documentation electronic schemes,
component and connection diagrams, EPLD source texts and oscillograms.
2. Hardware
As an introductory description, we will consider the block diagram (Appendix 6.1.).
Functionally, the hardware is broken down into three parts:
- PCI controller,
- serial EEPROM,
- Example application with 32bit latches and EPLD.
