What is the IntelliBusTM Protocol?
IntelliBus is a Boeing-developed serial databus
communication standard designed to network
sensors, actuators, and subsystems while providing
the simplicity necessary for miniature smart sensors,
the low latency needed for flight controls, the time
determinism required for data analysis, and the
distance for industrial control. IntelliBus permits the
integration of signal conditioning, analog-to-digital
conversion, and digital interfacing into a low-cost
package that can be installed in any sensor, actuator,
interface module, or system. Aeroflex Colorado
Springs (Aeroflex) licensed the IntelliBus standard to
market products in 2004.
IntelliBus has a low overhead that enables maximum
data transmittal, accommodates both sensors and
actuators for monitoring and control, and incorporates
fault avoidance features. Additionally, IntelliBus
accommodates a high sensor count per bus (over
500), allows synchronization between multiple
busses, simultaneous sampling capability, and
isochronous transmission with low jitter (+/- 500ps).
IntelliBus is time deterministic and enables high data
rates per bus (30, 15, and 7.5 Mbps) while
maintaining a low cost-per-node.
Aeroflex has developed a Network System product
family consisting of a Network Interface Controller
(NIC) and a Network Device Interface (NDI) to
address a variety of communication and control
network requirements in the Factory Floor Automation
and In-Vehicle Health Monitoring fields. Features
include:
A standard set of functions and services that
locate, configure, and operate a wide range of
transducer devices
A mechanism to acquire and distribute data:
• Synchronously
• At multiple sample rates
• Simultaneously with minimal acquisition jitter
Minimal network latency without strict constraints
on communication at the peripheral device
Support of device (node) memory containing
node information and automatic peripheral
configuration (at boot)
Multi-cast connectivity to a large number of
peripheral devices
A mechanism for any node to filter and trap
network data
Low-overhead time-deterministic device-todevice
data transfers
Data buffering to minimize network latency
Low-cost, EMC compliant physical layer: easymaintenance
twisted-pair copper
Capable of 30 Mbps data rate
Scalable hardware, firmware and software
A. Physical and Data Link layers (OSI layers 1-2)
Per the product features listed above, twisted pair
copper wiring is utilized with M-LVDS (Multipoint-Low-
Voltage Differential Signaling) data transceivers for
high-speed (30 Mbps) signaling, or RS-485
transceivers for lower speed applications. Off-theshelf
transceivers are used. Due to proprietary bit
sampling schemes in the receiver, no clock recovery
or re-syncing is necessary in the physical layer (layer
1), only signal level translation and output tri-stating is
required.
The typical Aeroflex NIC/NDI network system consists
of one bus controller and multiple nodes. Half duplex
data transmission occurs, where only the bus
controller or the addressed node is actively
transmitting data. More than one node may be
receiving the data. (Full-duplex communication is
possible on a single controller-to-node system. The
Data Link layer (layer 2) support is provided by two
hardware functions: the Network Interface Controller
(NIC) and the Network Device Interface (NDI).
The AX7000 Network Interface Controller (NIC)
The NIC function is the master bus controller for the
Aeroflex NIC/NDI network. Connecting directly to a
physical layer transceiver, the NIC controls the
scheduling of data communications on the network by
issuing commands to the NDI devices on the network.
Typically a PCI card in a host PC, the NIC uses a set
of IntelliBus protocol NIC opcodes which allow host
modification access to the NIC scheduler, as well as
direct access to network data.
The AX30 Network Device Interface (NDI)
The NDI function is the miniaturized interface chip
connecting peripheral devices onto the Aeroflex
NIC/NDI serial network. The IntelliBus protocol allows
each NDI device to support up to 16 peripherals (or
channels). These peripherals can range from simple
sensors or indicators to complex audio/visual
components. With 30 Mbps of throughput on the
physical bus, many NDI chips can be supported on a
single Aeroflex NIC/NDI network, with the maximum
addressable range of up to 509 channels per bus.
B. Presentation layer (OSI layer 6)
Included in the NDI is support for serial data
communications with peripherals via SPI, ISC, I2S
and UART ports. The number of ports (channels)
available within a specific NDI determine the pin count
and size of the device; thus, a range of NDI device
package sizes supports a variety of peripheral area
constraints. Input and output FIFO buffering is
provided within the NDI to support the difference in
data rates between the peripherals and the highspeed
Aeroflex NIC/NDI traffic rate.
C. Application layer (OSI layer 7)
Included in the NDI is flexible support for a large
variety of signal processing and signal conditioning
devices, such as:
Analog to Digital Converters
Digital to Analog Converters
Microcontrollers
Digital I/O (switches, indicator drive)
Inter-node communication

Network Interface Controller (AX7000-NIC)
GENERAL DESCRIPTION
The AX7000-NIC Network Interface Controller (NIC) is a
third generation controller design specifically to be used as
a controller in a PC based IntelliBus development system.
The card plugs directly into a 66Mhz, 32-bit 3.3V PCI
V2.2 compliant slot in a Pentium PC compatible computer.
The card supports two semi-independent IntelliBus serial
channels, which operate in asynchronous mode supporting
the IntelliBus Isochronous (IS) communications tier at data
rates up to15Mbps. The IntelliBus network channels are
implemented using the IntelliBus RS-485 physical layer
and can be configured in a Half or Full Duplex arrangement.
The card contains a 1K word deep FIFO for each of
the two network receiver channels. This allows real time
data collection using a standard PC operating system. All
control and data retrieval operations are handled by software
through registers implemented in the PCI interface.
The card supports a custom microcode instruction set that
is used to control the execution of a schedule. The microcode
is loaded, by software, into onboard schedule memory.
The card contains status lights for a real time
indication of the state of the network. The NIC controls all
I/O from an Interface Card.
The AX7000-NIC is manufactured at Aeroflex Colorado
Springs’ 104,000-square foot ISO-9001 certified facility.
Aeroflex Colorado Springs has been producing high-reliability
integrated circuits and circuit card assemblies for
the aerospace industry since 1980.

IntelliBus Interface
Data rates of 7.5Mbps, 15Mbps and 30Mbps are userselectable
via bit-rate select control inputs to the AX30NDI. A
simple MLVDS or RS-485 external transceiver is required for
the PHY layer. The internal Command Decoder interprets
network IntelliBus commands from the Network Interface
Controller, and performs the appropriate data transfer or
peripheral control.
External Serial Flash Interface
The AX30NDI device contains a bootup algorithm to support
a unique ID and unique self-configuration per port. This
bootup data is stored in external flash, and downloaded at
power-up into internal RAM via a serial interface. Electronic
Data Sheet information is also stored in the external flash and
is available for access by the IntelliBus Network Interface
Controller after the bootup procedure downloads data to RAM.
The flash interface is implemented as a standard SPI interface.
Peripheral Interface (Ports)
The number of available ports per NDI device type is defined
in Table 1. The three family members of the AX30NDI differ
only in the number of ports, thus affecting package size. Each
port supports an SPI protocol. As shown in the AX30NDI-09
Block Diagram, alternate serial protocols are supported: I2C,
I2S and UART. These alternate modes are user selected via pin
tie-offs. Each port contains three FIFOs for buffering the data
flow. A 16-word Output FIFO stores network data before
transferring to the peripheral when the proper (optionally
isochronous) IntelliBus command is decoded.
A 16-word Input Buffer and a second 16-word Input FIFO are
provided to allow isochronous data collection at peripheral
data rates, with previous-frame data output to the IntelliBus
network at IntelliBus data rates. Isochronous timedeterministic
data transfers to and from each port are
supported by the Trigger and Sync signals, decoded from
IntelliBus network commands. The PLL internal to the
AX30NDI provides peripheral clocking which is locked to the
Trigger signal. Three user-defined frequencies are available
for use at all channels, ranging from 48 KHz to 24.576 MHz.
Remote ID Inputs
The AX30NDI contains support for ID inputs which can be
read by the IntelliBus Network Interface Controller to
determine the physical location of each NDI located on a bus.
These signals are discrete inputs tied externally to Vdd or
Ground.

from the Network Interface Controller, and performs the
appropriate data transfer or peripheral control.
External Serial Flash Interface
The AX30NDIxxCAN device contains a bootup algorithm to
support a unique ID and unique self-configuration per port.
This bootup data is stored in external flash, and downloaded at
power-up into internal RAM via a serial interface. Electronic
Data Sheet information is also stored in the external flash and
is available for access by the IntelliBus Network Interface
Controller after the bootup procedure downloads data to RAM.
The flash interface is implemented as a standard SPI interface.
Peripheral Interface (Ports)
The number of available ports per NDI device type is defined
in Table 1. The three family members of the AX30NDIxxCAN
differ only in the number of ports, thus affecting package size.
Each port supports an SPI protocol. As shown in the
AX30NDI-010CAN Block Diagram, alternate serial protocols
are supported: I2C, I2S and UART. These alternate modes are
user selected via pin tie-offs. Each port contains three FIFOs
for buffering the data flow. A 16-word Output FIFO stores
network data before transferring to the peripheral when the
proper (optionally isochronous) IntelliBus command is
decoded.
A 16-word Input Buffer and a second 16-word Input FIFO are
provided to allow isochronous data collection at peripheral
data rates, with previous-frame data output to the IntelliBus
network at IntelliBus data rates. Isochronous timedeterministic
data transfers to and from each port are
supported by the Trigger and Sync signals, decoded from
IntelliBus network commands. The PLL internal to the
AX30NDI provides peripheral clocking which is locked to the
Trigger signal. Three user-defined frequencies are available
for use at all channels, ranging from 48 KHz to 24.576 MHz.
Remote ID Inputs
The AX30NDIxxCAN contains support for ID inputs which
can be read by the IntelliBus Network Interface Controller to
determine the physical location of each NDI located on a bus.
These signals are discrete inputs tied externally to Vdd or
Ground.
CAN Bus Interface
The AX30NDIxxCAN contains a CAN controller and PHY
module implementing a bridge between the IntelliBus network
and a CAN 2.0B network.
