FireBird Single CoaXPress Low Profile

The FireBird Single CoaXPress Low Profile is a member of Active Silicon’s state-of-the-art FireBird frame grabber family.

FireBird is designed for ultimate performance using Active Silicon’s proprietary DMA engine technology, “ActiveDMA”. This technical innovation applies RISC based processor techniques and guarantees zero CPU intervention, and high-speed and real-time image data transfers.

The FireBird Single CoaXPress Low Profile can be shipped with either a 2U low-profile PC card bracket or a full-height PC card bracket.

CoaXPress is a leading transmission standard for high-speed imaging in professional and industrial applications. The CoaXPress link supports up to 6.25 Gbps data rates, along with device power up to 13W and device control at 20 Mbps – all on a single coax cable. Very long cable lengths are supported – up to 40m at 6.25 Gbps and over 100m at 3.125 Gbps using Belden 1694A cable – or even longer lengths using thicker cables. Active Silicon was one of the primary authors of the CoaXPress international standard, which is hosted by the JIIA (Japan Industrial Imaging Association). All our CoaXPress products are certified compliant to the specification through the JIIA CoaXPress Product Certification Program.

FireBird is supported by Active Silicon’s software development kit, ActiveSDK, which allows rapid system development and integration and is available as a separate item. It provides comprehensive example applications and optimized libraries, and supports a variety of operating systems via a common API, including Windows, Linux (64-bit) and QNX. Drivers for third-party applications are also available such as Cognex VisionPro, HALCON, Common Vision Blox, StreamPix, LabVIEW etc. Full GenICam support is included in the drivers and this includes a GenTL Producer for data streaming as well as register accesses. In addition to functions that control the hardware, the libraries include general purpose functions for the manipulation and display of images. A separate datasheet describes the SDK in detail.

Model NameFireBird Single CoaXPress Low Profile
CoaXPress InterfaceA 75 Ohm Micro-BNC connector (also known as HD-BNC) provides one link operating at all CXP speeds up to 6.25 Gbps. Up to 17W is available to power cameras via Power over CoaXPress (PoCXP), with 13W available at the camera according to the CoaXPress specification.

An LED alongside the Micro-BNC shows the link status according to the CoaXPress specification.
Buffer Memory4-lane Gen2 interface typically providing 1.7 Gbytes/sec transfer from FireBird to the PC, subject to PC performance.
PCI Express4-lane Gen2 interface typically providing 1.7 Gbytes/sec transfer from FireBird to the PC, subject to PC performance.
I/OThe following I/O lines are provided for triggers, shaft encoders, exposure control
and general I/O:
• 4 opto-isolated inputs.
• 4 opto-isolated outputs.
• 4 TTL inputs, 5V tolerant.
• 4 TTL I/O, 5V logic.
• 4 RS-422 inputs.
• 4 RS-422 outputs.
All these I/O signals are provided on a 50-way header on the FireBird board.
A 15-way D-Type connector is located on the front panel and allows access to a subset of the above I/O:
• 2 opto-isolated inputs.
• 3 TTL I/O, 5V logic.
• 2 RS-422 inputs.
• 1 RS-422 output.
Acquisition Control:The acquisition control functionality is used to determine which video frames to acquire from the camera. The system can be configured for a single trigger event to acquire all subsequent frames, a trigger event per frame, or continuous acquisition irrespective of the trigger condition.

The trigger event is programmable to be level or edge sensing via the control inputs (see the I/O section for more details) which can also be filtered to removed noise. Additionally, a delay block allows acquisition to be delayed by a defined time.
Trigger ControlA comprehensive trigger control block allows triggers to be sent both over CoaXPress and to the control outputs (see the I/O section for more details).

These triggers can be generated from the control inputs, an astable timer, and a software trigger. The selected trigger source can be filtered to remove noise, and can trigger monostable timers to provide defined width pulses, e.g. for exposure control or lighting control. Additionally, delay blocks allow the trigger to be shifted by a defined time.

Additional modes interface to shaft encoders, including support for a quadrature encoder with the option to reject mechanical jitter from the encoder.
Region of InterestThe Region Of Interest (ROI) feature controls which part of the output image to acquire. In areascan mode, this is a rectangular region with a programmable width, height and x / y offset.

Linescan mode is similar, allowing control of the width and x offset, with the height control being used to package the data into pseudo frames for subsequent processing by the user’s application.
Status LEDsStatus LEDs are fitted to provide feedback on the camera connectivity and FireBird activity:
Camera connectivity:
• Camera connected / not connected.
• Data transfer from camera.
FireBird activity:
• FPGA configuration.
• PCIe access.
PCI Express InterfacePCI Express bus four lane Gen2 interface to Specification Revision 3.1, with a max payload size of 512 bytes.

FireBird Single CXP-6 Low Profile supports both Short (32-bit) and Long (64-bit) Address packets. It also generates Posted Writes for image data, thus achieving transfer rates in excess of 1.7 GBytes/sec, subject to host performance.
