Falcon4 86M Cameras
CLHS limits the start and stop location of the ROI to a multiples of 32 pixels. The maximum line
rate is limited by the sensor when not limited by the CLHS cable or by the PCIe transfer. The sensor
is limited to a 125 kHz maximum line rate.
The CLHS cable has approximately 2.1 GByte / sec bandwidth for seven lanes. The XTIUM X8 frame
grabber has about 3.2 GByte / sec across the PCIe bus and can support the full frame rate of the
camera.
Sensor Block Diagram & Pixel Readout
Pixels are read from left to right, top to bottom. The data for each line is transferred from the
sensor to 7 CLHS data lanes. CLHS is a packet-based protocol therefore the concept of taps or tap
geometry does not apply; the frame grabber reconstructs the images based on the information
contained in the packet, regardless of which data lane is used for the transfer.
