12 Customer Designed 4000-OEM Boards and Camera Interface Options
Most common customer configurations integrate the SightLine OEM board designs into a gimbal
controller or other boards.
All SightLine OEM hardware provides camera input options through SightLine adapter boards to
convert camera data into parallel digital video for acquisition. It is often beneficial to integrate both the
OEM and the adapter board functionality into customer hardware.
The 4000-OEM provides three options for camera acquisition in a custom designed 4000-OEM board
that are described in the next sections.
12.1 Using the Lattice FPGA
The Lattice crosslink FPGA on the 4000-OEM converts parallel digital video into MIPI format data that is
captured by the MIPI-CSI2 interface on the SOM.
Connector: Appears in software as:
J6 (3000-Adapter board required)
Camera 0 (Cam 0)
J9 (MIPI) Camera 1 (Cam 1)
J8 USB3 (USB camera) Camera 2 (Cam 2)
In this case customers can design in a single camera adapter board or add a separate FPGA on the
input to perform camera switch operations. This approach has the advantages of a simple design and
assured MIPI format compatibility with the 4000-SOM since the Lattice FPGA does the MIPI generation.
The Lattice FPGA provides tight integration with the 4000-SOM through an I
2
C register interface. This
allows the SOM to reset the FPGA state machine (synchronized to frame sync) by setting a bit in the
register interface.
12.2 Not Using the Lattice FPGA
The customer can integrate the camera acquisition, camera switch, and parallel to MIPI conversion in a
single FPGA eliminating the need to design in the Lattice crosslink FPGA. This is a more advanced
design and is less tightly coupled with the 4000-SOM and adds the complexities of generating MIPI
signaling compatible with the 4000-SOM supported formats. This approach may require purchasing a
MIPI IP design for the FPGA. See important design details and requirements in
EAN-MIPI-Cameras .
12.3 MIPI Camera Data Acquisition
MIPI format camera data can also be captured directly by the MIPI CSI0 interface on the SOM MIPI Port
J9 (Cam 1) . For supported MIPI cameras and formats see EAN-MIPI-Cameras .
