PXIe-1090 Backplane Overview
Interoperability with CompactPCI
The PXIe-1090 design provides 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
ThunderboltTM 3 Interface
The PXIe-1090 chassis has a built-in Intel Thunderbolt 3 interface accessible through two
Thunderbolt 3 ports on the back of the chassis. This enables control of the PXIe-1090 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-1090 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.
4| ni.com | PXIe-1090 User Guide
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. 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-1090 via
a Thunderbolt port on the chassis, as shown in the following figure.
Figure 3. Example of a Basic MXI-Express Thunderbolt Link Topology
Thunderbolt Bus Extension
You can daisy-chain from a PXIe-1090 controlled by a PC to an additional Thunderbolt 3
compatible device. The following figure shows how you can use a PXIe-1090 to connect
multiple Thunderbolt 3 compatible devices to a PC in a daisy-chain topology.
PXIe-1090 User Guide | © National Instruments Corporation | 5
Figure 4. Example of a Daisy-Chain Thunderbolt Link Topology
Hybrid Peripheral Slot
The hybrid peripheral slot can accept the following peripheral modules:
• A PXI Express peripheral with x8, x4, or x1 PCI Express link.
• A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link.
• 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 slot provides 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 right.
PXI Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with
adjacent peripheral slots.
The backplane routes PXI Local Bus 6 between PXI slots. The left local bus 6 from slot 2 and
right local bus 6 from slot 3 are not routed anywhere.
Local bus signals may range from high-speed TTL signals to analog signals as high as 42 V.
6| ni.com | PXIe-1090 User Guide
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.
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-1090 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.

You must maintain adequate clearance between the chassis and surrounding equipment, heat
generating devices, and air flow blockages to ensure proper cooling. Minimum cooling
clearances are shown in the following figure. For rack mount applications, adequate forced air
ventilation is required. For benchtop or rack mount applications, additional cooling clearances
may be required for optimal air flow and reduced hot air recirculation to the air inlet fans.

(1.75 in.)
Note Failure to provide these clearances may result in undesired thermal-related
issues with the chassis or modules.
To aid in thermal health monitoring for either rack or benchtop use, you can monitor the
chassis intake temperatures in Measurement & Automation Explorer (MAX) to ensure the
temperatures do not exceed the ratings in the Operating Environment section of the PXIe-1090
Specifications.
Additionally, many PXI modules provide temperature values you can monitor to ensure
critical temperatures are not exceeded. Increasing chassis clearances, ventilation, reducing
external ambient temperatures, and removing nearby heat sources are all options for improving
overall chassis thermal performance.
Chassis Ambient Temperature Definition
The chassis fan control system uses ambient intake air temperatures for controlling fan speeds
when in Auto mode. These temperatures may be higher than ambient room temperature
depending on surrounding equipment and/or airflow blockages. Ensure ambient intake
temperatures do not exceed the ratings in the Operating Environment section of the PXIe-1090
Specifications. You can monitor the module ambient intake temperatures in NI Measurement
& Automation Explorer (MAX).
Setting Fan Speed
The PXIe-1090 chassis supports multiple fan operating modes. Refer to the Fan Mode section
for more information.
Installing Filler Panels
To maintain proper module cooling performance, install filler panels (one is provided with the
chassis) in unused or empty slots. Secure with the captive mounting screws provided.
Installing Slot Blockers
You can improve the cooling performance of the chassis by installing optional slot blockers.
Refer to the NI website at ni.com/info and enter the Info Code slotblocker for more
information about slot blockers.
