Description

Frame Grabber Overview

The FireBird Single CoaXPress Low Profile is a member of Active Silicon’s 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 6.25 Gbps data rates, along with device power up to 13 W and device control at 20 Mbps all on a single coax cable. Very long cable lengths are supported up to 40 m at 6.25 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 Silicons PHX software development kit (SDK), which allows easy migration for customers using Phoenix frame grabbers. The PHX SDK is available as a separate item, and allows rapid system development and integration. It provides comprehensive example applications and optimized libraries, and is available for a variety of operating systems via a common API, including Windows and Linux (32 bit and 64 bit environments) as well as Mac OS X 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. As well as 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.

  • Fast PCI Express 8-lane Gen2 interface.
  • RISC based DMA engine gives zero CPU acquisition.
  • Comprehensive I/O.
  • Supports PoCXP (Power over CoaXPress).
  • Standard half-length PCI form factor.
  • Full GenICam support (including GenTL Producer).
  • Supported by the proven PHX SDK.

Specification


  1xCXP6
CoaXPress Interface A Micro-BNC connector provides one link operating up to 6.25 Gbps and providing up to 13W of power via Power over CoaXPress (PoCXP). An LED alongside the Micro-BNC shows the link status according to the CoaXPress specification.
PCI Express 4-lane Gen2 interface to support up to 20 Gbps 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.

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.
Acquistion 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.
Region of Interest

The Region Of Interest (ROI) feature controls which part of the output image to acquire.
This option is available in areascan or linescan mode.

Status LEDs Status LEDs are fitted to provide feedback on the camera connectivity and FireBird activity
PCI Express Schnittstelle

PCI 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.

The board requires 16 MBytes of address space

CoaXPress FireBird Single CXP-6 Low Profile conforms to v1.1 of the CoaXPress specification. Micro-BNC ready for CXP v2.0.
