These versions are designated with an
_F
in the FPGA file name, and use a FIFO to create more
blanking area by:
-
buffering up the first part of a line of video in a FIFO while outputting the MIPI header packet,
-
continuing to buffer in additional input pixel data,
-
simultaneously reading data out of the FIFO at an increased output pixel clock rate.
Table 17
shows the FIFO versions of FPGA that support between 1 and 64 horizontal pixel blanking
cameras.

Width and Height Requirements
Both the width and height must be multiples of eight.

Additional FPGA Versions and naming
Some early versions of the FPGA code only support a fixed width in pixels. These versions have the
fixed width in their name.

Maximum Width and Height
The capture width and capture height are limited to 4112 x 3040.
The processed ROI is limited to 4K
3840 x 2160.
The ROI can be moved around in the full image by changing the col and row.

MIPI Port J9 (Cam 1)
The MIPI port provides an interface directly connecting MIPI cameras to the 4000-OEM. This port
provides camera power and camera configuration through I
2
C. For details on supported MIPI cameras
and formats see
The MIPI port can also be used to connect SightLine Video Input adapter boards through the 4000-MIPI
adapter board. For details on the 4000-MIPI and Video Input Boards, see the

Camera Input Adapter Board IDs
Each SightLine camera adapter board is assigned a unique adapter ID to simplify setup and
configuration. This applies to any board connected to J6 or J9 on the 4000-OEM (J10 on the SLA-4000-
MIPI adapter board).
See the 3000-4000-OEM Camera Input Adapter Board ID table
for a list of camera input adapter boards and IDs.
