PXIe-1083 Backplane Overview
Interoperability with CompactPCI
The design of the PXIe-1083 provides you the flexibility to use the following devices in a
single PXI Express chassis:
• PXI Express compatible products
• CompactPCI Express compatible Type-2 peripheral products
• PXI peripheral products modified to fit in a hybrid slot
• Standard CompactPCI peripheral products modified to fit in a hybrid slot
MXI Interface
The PXIe-1083 chassis has a built-in Intel Thunderbolt 3 interface accessible through two
Thunderbolt 3 ports on the front of the chassis. This enables control of the PXIe-1083 from a
host PC that includes a Thunderbolt 3 port and is running a native (nonvirtualized) operating
system that supports Thunderbolt connectivity.
Note The PXIe-1083 chassis does not include a slot 1; the Thunderbolt 3 ports
replace this slot.
Thunderbolt technology is transparent to device drivers, so no additional software is needed
for CompactPCI Express-level support for PXI Express devices in connected chassis.
Note For full PXI/PXI Express functionality such as chassis and controller
identification, trigger routing, and slot detection, install the latest version of PXI
Platform Services. This software is included with your kit; you also can find it at
ni.com/downloads by searching for PXI Platform Services.
The link between the PC and the chassis is a Thunderbolt 3 link. This link is a dual-simplex
communication channel comprised of differentially driven signal pairs. The link can transmit
at a rate of up to 40 Gbps in each direction simultaneously.
Basic MXI-Express Thunderbolt Systems
The simplest MXI-Express Thunderbolt system consists of a PC connected to a PXIe-1083 in
the controller slot of a PXI Express chassis, as shown in the following figure.
6| ni.com | PXIe-1083 User Guide
Figure 3. Example of a Basic MXI-Express Thunderbolt Link Topology
Thunderbolt Bus Extension
You can daisy-chain from a PXIe-1083 controlled by a laptop to an additional Thunderbolt 3
compatible device. The following figure shows how you can use a PXIe-1083 to connect
multiple Thunderbolt 3 compatible devices to a PC in a daisy-chain topology.
Figure 4. Example of a Daisy-Chain Thunderbolt Link Topology
Backwards Compatibility
NI recommends connecting the PXIe-1083 to a Thunderbolt 3 port on the host PC using a
Thunderbolt 3 cable. Because Thunderbolt 3 is backwards-compatible with previous
Thunderbolt generations, it may be possible to use adapters to establish connections with host
PCs or devices with previous-generation Thunderbolt ports. Data throughput performance may
vary between Thunderbolt generations.
Hybrid Peripheral Slots
The chassis provides five (5) hybrid peripheral slots as defined by the PXI-5 PXI Express
Hardware Specification: slots 2 through 6. A hybrid peripheral slot can accept the following
peripheral modules:
• A PXI Express peripheral with x8, x4, or x1 PCI Express link through a switch to the
Thunderbolt 3 controller (and host PC). Each PXI Express peripheral slot can link up to a
PXIe-1083 User Guide | © National Instruments | 7
Gen-2 x1 PCI Express, providing a maximum nominal single-direction bandwidth of 500
MB/s.
• A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link to the host
PC through a PCI Express switch and Thunderbolt 3 controller.
• A hybrid-compatible PXI Peripheral module modified by replacing the J2 connector with
an XJ4 connector installed in the upper eight rows of J2. Refer to the PXI Express
Specification for details. The PXI peripheral communicates through the backplane’s 32-
bit PCI bus.
• A CompactPCI 32-bit peripheral on the backplane’s 32-bit PCI bus.
The hybrid peripheral slots provide full PXI Express functionality and 32-bit PXI functionality
except for PXI Local Bus. The hybrid peripheral slot connects to only PXI Local Bus 6 left
and right.

PXI Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with
adjacent peripheral slots to the left and right.
The backplane routes PXI Local Bus 6 between adjacent PXI slots. The left local bus 6 from
slot 2 and right local bus 6 from slot 6 are not routed anywhere.
The backplane routes PXI Local Bus between all slots. Local bus signals may range from
high-speed TTL signals to analog signals as high as 42 V.
Initialization software uses the configuration information specific to each adjacent peripheral
module to evaluate local bus compatibility.

PXI Trigger Bus
All slots share eight PXI trigger lines. You can use these trigger lines in a variety of ways. For
example, you can use triggers to synchronize the operation of several different PXI peripheral
modules. Modules can pass triggers to one another on the lines, allowing precisely timed
responses to asynchronous external events the system is monitoring or controlling.
The PXI trigger lines from adjacent PXI trigger bus segments can be routed in either direction
across the PXI trigger bridges through buffers. This allows you to send trigger signals to, and
receive trigger signals from, every slot in the chassis. Static trigger routing (user-specified line
and directional assignments) can be configured through Measurement & Automation Explorer
(MAX). Dynamic routing of triggers (automatic line assignments) is supported through certain
NI drivers like NI-DAQmx.
Note Although any trigger line may be routed in either direction, it cannot be
routed in more than one direction at a time.

System Reference Clock
The PXIe-1083 chassis supplies PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 to every
peripheral slot with an independent driver for each signal.
An independent buffer (having a source impedance matched to the backplane and a skew of
less than 250 ps between slots) drives PXI_CLK10 to each peripheral slot. You can use this
common reference clock signal to synchronize multiple modules in a measurement or control
system.
An independent buffer drives PXIe_CLK100 to each peripheral slot. These clocks are matched
in skew to less than 100 ps. The differential pair must be terminated on the peripheral with
LVPECL termination for the buffer to drive PXIe_CLK100 so that when there is no peripheral
or a peripheral that does not connect to PXIe_CLK100, there is no clock being driven on the
pair to that slot.
An independent buffer drives PXIe_SYNC100 to each peripheral slot. The differential pair
must be terminated on the peripheral with LVPECL termination for the buffer to drive
PXIe_SYNC100 so that when there is no peripheral or a peripheral that does not connect to
PXIe_SYNC100, there is no SYNC100 signal being driven on the pair to that slot.

PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 have the default timing relationship
described in the following figure.
