Frame Grabber Overview

FireBird Single CXP-12 is a member of Active Silicons state-of-the-art FireBird frame grabber family.

CoaXPress is a new digital transmission standard that allows high speed data from a device such as a camera to be transferred to a host such as a frame grabber. The CoaXPress link supports up to 12.5 Gbps data rates, along with device power up to 13 W and device control at 42 Mbps all on a single coax cable. Very long cable lengths are supported up to 35 m at 12.5 Gbps and over 100 m at 3.125 Gbps. Active Silicon was one of the primary authors of the CoaXPress specification which is now a JIIA (Japanese Industrial Imaging Association) standard.

FireBird is supported by Active Silicon’s software development kit, ActiveSDK. This is available as a separate item and allows rapid system development and integration. It provides comprehensive example applications and optimized libraries, and supports a variety of operating systems via a common API, including Windows, Linux (64-bit environments) 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. Additional to functions that control the hardware, the libraries include general purpose functions for the manipulation and display of images. A separate datasheet describes ActiveSDK in detail.


  • CoaXPress gives high speed data, power, and camera control all over a single cable.
  • High performance with 50 Gigabits per second input rate.
  • Fast PCI Express 4-lane and 8-lane Gen3 interface.
  • RISC based DMA engine gives zero CPU acquisition.
  • Comprehensive I/O.
  • Supports PoCXP (Power over CoaXPress).
  • Micro BNC Connector
  • Standard half-length PCI form factor.
  • Full GenICam support (including GenTL Producer).
  • Supported by the proven ActiveSDK.


  1x CXP12 / 4-lane or 8-lane
CoaXPress Interface Four Micro-BNC connectors provide four links each operating at all CXP speeds up to 12.5 Gbps, and each providing up to 13W of power via Power over CoaXPress (PoCXP). LEDs on the end bracket BNC show the link status according to the CoaXPress specification
Buffer Memory Up to 2.5 GBytes of DDR4 memory is fitted for buffering between the CoaXPress interface and the PCI Express bus.
PCI Express Options for a four-lane or eight-lane Gen3 interface to support up to 6.8 Gbytes/sec transfer from FireBird to the PC.
I / O

The 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.

Power Input An 8-way PCI Express Graphics (PEG) connector is provided to connect to a 6- or 8-way PEG connector from the PC power supply. This is only needed for PoCXP.
Fan Controller The fan speed is linked to the temperature of the FPGA die for optimum cooling and noise level.
PCI Express Interface

PCI Express Bus four or eight lane Gen3 interface to Specification Revision 3.0, with a max payload size of 512 bytes.

FireBird Quad CXP-12 supports both Short (32-bit) and Long (64-bit) Address packets. It also generates Posted Writes for image data, thus achieving transfer rates up to 6.8 Gbytes/sec, subject to host performance.
