BCON Data Output

The data output by the four data lanes (X0, X1, X2, X3) consists of the following information:
Frame valid bit (FVal): Indicates that a valid frame is being transmitted.

Line valid bit (LVal): Indicates that a valid line is being transmitted.

Frame information (FrameInfo): Includes information about the pixel format and the number

of pixels per clock cycle. Sent before each frame transmission.
Pixel data (Line 1, Line 2, ..., Line n): Pixel data, line by line.

Line checksum (Cksum 1, Cksum 2, ..., Cksum n): Check sum for each line of pixel data.

Sent after each line transmission.
BCON output bits (Output 0 and Output 1): Two bits that can be used to transmit camera

output signals, e.g. Flash Window or Exposure Active.
Frame information, pixel data, and line checksums are transmitted on a common 24-bit image data
channel ("Data").

The BCON interface does not provide data flow control. Also, in contrast to the CameraLink
interface, the BCON interface does not provide a data valid bit (DVal). Only FVal and LVal are used
as synchronization signals.
Whenever FVal is low and the camera is not sending FrameInfo or Cksum data, a
sync pattern is transmitted. This allows you to set up the correct word alignment.
