Hardware Overview
This chapter presents an overview of the hardware functions of your MXI-3
system, and explains the operation of each functional unit.
Functional Overview
The MXI-3 system is a PCI-PCI bridge that needs no software for normal
operation. When the desktop PC or the CompactPCI/PXI controller
finds the primary interface of the MXI-3 card, it opens memory windows
in the card and searches for PCI devices through those windows using PCI
transactions. The PC recognizes all devices on the secondary bus to be on
a single PCI bus.
Figure 3-1, MXI-3 Block Diagram, shows the basic architecture of the
MXI-3 system. The MXI-3 card interfaces to the PCI bus with the National
Instruments MXI-3 ASIC. The ASIC converts PCI transactions into a
20-bit wide parallel bus. A parallel to serial converter transmits the 20-bit
data as serial data at 1.5 GBytes/s. If you are using copper cable, the system
sends the unmodified serial data through the cable. If you are using
fiber-optic cable, the system converts the serial data to light using a
VCSEL module.
On the other side of the system, the MXI-3 card receives the data, using
high-speed photodetectors to convert light signals back to digital data if
necessary. A serial to parallel converter then converts the digital serial data
to the original 20-bit wide packets of data for the MXI-3 ASIC. MXI-3 then
recreates the PCI transaction with appropriate modifications.

By plugging a PXI MXI-3 module into any of slots 2 through 8 of a
PXI/CompactPCI chassis and a PXI MXI-3 module into Slot 1 of an
additional PXI/CompactPCI chassis and connecting them with a cable,
modules detect the slot in which they reside and automatically configure
themselves as primary or secondary. In accordance with the PCI-to-PCI
Bridge specification, up to 254 chassis can be linked to a single
desktop PC.

Chapter 3
Hardware Overview
Serial Transmitter
The serial transmitter is a parallel-to-serial data converter. The
parallel-to-serial converter serializes the 20-bit wide parallel data from the
MXI-3 ASIC and sends it to the transceiver.
Serial Receiver
The serial receiver is a serial-to-parallel data converter. The
serial-to-parallel converter deserializes the data from the receiver and
supplies the 20-bit wide parallel data to the MXI-3 ASIC.
High Speed Serial Data Connector (HSSDC)
Receptacle
The HSSDC 8-position right-angle receptacle assembly interfaces the
electrical data to the copper serial cable.
High Speed Serial Data Connector (HSSDC) Cable
The HSSDC 8-position cable assembly is the copper medium through
which the serial data is transferred.
Gigabit Ethernet Link (Duplex SC Connector)
The Gigabit Ethernet Link Duplex SC Connector uses VCSEL technology
to convert electrical data into laser light, and transmits the data across a
fiber-optic cable. It also converts the laser light back to electrical data after
receiving it from the cable.
Gigabit Ethernet Link (Multi-Mode Fiber-Optic
Cable)
The Gigabit Ethernet Link Multi-Mode Fiber-Optic Cable is the medium
through which the laser light is transferred.
MXI-3 Cable Options
Both copper and fiber-optic cables are available for your MXI-3 system.
Copper links are the least expensive interconnect and can span up to
10 meters between systems. Fiber optic links offer connections
between systems separated by up to 200 meters without repeaters.
National Instruments offers 2 meter, 5 meter, and 10 meter copper
cables and a 30 meter fiber optic cable as described in Table 3-1.
