Chapter 2 General Description
General description of APX-3302
2.1 Product Summary
APX-3302 is a LowProfile type PCI-Express frame grabber which supports CameraLink interface.
On-board mini SDR26 pin connector allows connecting up to two independent CameraLink
Base Configuration cameras for each. It has an I/O interface circuit compatible with APX-3312 that provides
image acquisition control in conjunction with external devises.
Cautions:
If you insert our products to x 16-lane port that is specified for the graphics card on the PC or motherboard,
it may not work correctly. These lanes are not in operation guarantee because these lane's specification
are not clear, and might be made to be able to maximize the capabilities of the graphics card.
2.2 Feature
Features of APX-3302

・
On-board APX-3312 compatible external I/O interface enables coordination with external device or
generates interrupts
・
Strobe timing output allows to notify the exposure timing to external lighting devices
・
256MB of on board MEGA-FIFO image buffer for each camera
・
RoHS compliant
※
MEGA-FIFO architecture
MEGA-FIFO architecture is a structure to store the image data from the camera in large capacity buffer
on board temporarily, then it transfers the image data to host memory via the buffer.
Hardware offers fastest operation of buffer input by the camera.
(Base Configurationcamera:Max 85MHzx32bit
＝
340MByte/sec)
It is possible to acquire the image until the buffer capacity is full even the bandwidth of PCI-Express is
lower then the frame rate of a camera.
