SECTION 2 - TECHNICAL DESCRIPTION
BASIC ARCHITECTURE OF PCI EXTENSION MODULE
The 51-921 and 41-921 extension module is basically a PCI-to-PCI bridge. The PCI-to-PCI bridge function in
the 51-921 and 41-921 supports legacy address routed trafc, which provides 100% capability with PCI drivers,
application software,
BIOS, O/Ss, etc. This functionality allow users to transfer their designs without extra effort. The functional block
diagram of 51-921 and 41-921 is shown in Figure 2.1.
The interface uses serial interconnect technology operating at 622 Mbps based on low voltage differential signaling
(LVDS). Each interface connection uses two data links, named as Link 1 and Link 2. Each link is divided into
transmit (TX) and receive (RX). Four TX and RX differential pairs in each link are used to provide 2.5Gbps full duplex
link bandwidth or 5Gbps of total bandwidth. Incorporated with the high speed serial LVDS, it is easy to extend the
transmission up to 10 meters through shielded twisted pair copper cables.
Inside the PCI-to-PCI bridge, a PCI-to-StarFabric/StarFabric-to-PCI converter is used to translate PCI transactions
into StarFabric frames and StarFabric frames into PCI transactions. The PCI interface of the 51-921 and 41-921 is
capable of 64-bit/66MHz. The maximum data throughput can up to 528Mbytes/s. The secondary side PCI interface
of PCI-to-PCI bridge is responsible to the central resources and system clocks generation.
Figure 2.1 Block diagram of 51-921 and 41-921
BUS ARCHITECTURE
Each 51-921 and 41-921 extension module has two link ports. Users can use one of them to extend PCI bus to a
PXI chassis or both of them to extend PCI bus to two PXI chassis.
The following gure represents an example of the PCI extension architecture. The desktop PC or PXI system
extends the PCI bus to two PXI chassis via 51-921 and 41-921 modules. From the system view, the three 51-921
and 41-921 modules act as three PCI-to-PCI bridges. Thus the serial interconnection between these bridges is also
a bus, i.e. bus 1 in this example, although it’s not PCI architecture.

pickering SECTION 3 - INSTALLATION
HARDWARE CONFIGURATION
Jumper Setting (only for 41-921-001)
The 41-921 includes two jumpers that can be set by the user to enable a spread spectrum PCI clock or force 33 MHz
operation. For many applications the status of these jumpers will not effect system operation.
Spread Spectrum Jumper Setting
When 41-921-PXI is plugged into the chassis system slot 1, it provides a discrete clock signal to each of the
peripheral slots (dened as a PCI clock CLK0, CLK1, CLK2, CLK3, CLK4, CLK5, and CLK6).
An important feature of the 51-921 and 41-921 extension modules is that they support 33MHz/66MHz clock operating
environment. As the system clock frequency increases, electromagnetic interference (EMI) becomes an increasing
challenge for the system designers. 41-921-PXI can provide a spread-spectrum clock generator to help user to
deal with this difcult task. Spread spectrum clocking speeds up and slows down the clock within a few percent of
its fundamental frequency. By reducing the average amplitude in a given BW, the system will more likely meet EMI
emission compliance standards. The use of spread spectrum clocking distributes the energy that was originally
concentrated on one frequency over a wider band. This method dramatically reduces the amount of EMI in a narrow
bandwidth. Use the settings shown in Figure 3.1 to control the spread spectrum clock generator.
Figure 3.1 - Spread Spectrum Jumper Settings
M66EN Jumper Setting
41-921-PXI supports 64-bit or 32-bit PCI buses operating at 66MHz or 33MHz. A bundled link can support
the full bandwidth of 64-bit/66MHz PCI bus. You can utilize the following conguration to set the operation
frequency of your system.
Figure 3.2 - M66EN Jumper Settings
A 51-921 and 41-921 interface supports the following primary and secondary bus frequency combinations:
• 66MHz primary bus, 66MHz secondary bus
• 66MHz primary bus, 33MHz secondary bus
• 33MHz primary bus, 33MHz secondary bus
51-921 and 41-921 doesn’t support 33MHz primary/66MHz secondary bus operation.

b. For use in primary PXI bus – Choose any unused PXI or CompactPCI peripheral slot except slot 1 (Slot 1
is reserved for the system controller.)
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on
the top and bottom of the slot.
WARNING: Do not raise the injector/ejector handle whilst inserting the module. The module will not insert properly
unless the handle is in its downward position.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/
ejector rail (refer to Figure 3.4).
6. Raise the injector/ejector handle until the module rmly seats into the backplane. The front panel of the module
should be ush with the front panel of the chassis.
7. Screw the front panel of the module to the front panel mounting rail.
8. Fit the cabling appropriately to the system design (See Section 1 and later in this section)
9. After connecting the PC to the PXI chassis or to link multiple chassis, power-up the system as follows:
a. For a system comprising a PC and one chassis, power up the chassis before powering up the PC.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and nally turn ON the PC or chassis containing the system controller.
10. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up
sequence.

SECTION 3 - INSTALLATION
INTERCONNECTION CABLING
Because 51-921 and 41-921 extension module functions as a standard PCI-to-PCI bridge, it can take advantage
of a variety of extension congurations. Figure 3.5 & 3.6 show the most basic PCI extension conguration. Each
primary extension module can connect to two secondary extension modules. Figure 3.7 & 3.8 show the Star
and Daisy-chain congurations to extend to more than two PXI chassis. Each 51-921 to 41-921 (or 41-921 to
41-921) connection requires two connections to be made (Link 0 and Link 1), providing an up link and a downlink
respectively. Please follow these steps to link the primary and secondary extension modules:
1. Connect the cables to both primary and secondary extension modules. Two cables are required for linking the
primary and secondary modules. The rst cable is used for connecting the PCI to PXI communication link. This
cable is connected from L0 Tx on the 51-921 PCI card to the L0 Rx on the 41-921 PXI module.
The other is used for connecting the PXI to PCI communication link. The cable is connected from L0 Rx on the
51-921 PCI card to the L0 Tx on the 41-921 PXI card. Please refer to Figure 3.5 and 3.6 for connection details.
2. Power on the system with the secondary extension module rst (PXI Chassis). Then turn on the system with the
primary extension module (Computer).
Notes:
• If the interconnection is correct, the indicated LED of primary extension module is extinguished (OFF) and the
LED of secondary extension module is illuminated (ON).
• If you turn on the system with primary extension module rst and then secondary extension module, the indicator
LED’s of both modules will keep blinking.
• If the communication between primary and secondary extension modules is broken, the indicated LED of primary
module is illuminated (ON) and the LED of secondary module is extinguished (OFF).
• If Star or Daisy-chain congurations are implemented, please always turn on the secondary system rst.
