5.2.3
Frame Valid Bit and Line Valid Bit
The frame valid bit (FVal) and the line valid bit (LVal) indicate that a valid frame or line is being
transmitted.
LVal and FVal are transmitted on data lane X0 at position 2 and 3 (see Figure 21 on
).
5.2.4
Frame Information
As shown in Figure 20 on
, a "FrameInfo" block is sent before each frame transmission.
Each FrameInfo block includes the following information:
Pixel format valid for the following pixel data.
Number of pixels per clock cycle.
Frame information is always transmitted on
bits 0 through 7
of the 24-bit data channel:
If you are only using 8-bit pixel formats, e.g. because you are using a monochrome
camera, the X2 and X3 data lanes are never active. Accordingly, if you are only
using 8-bit or 12-bit pixel formats, X3 is never active.
Basler recommends, however, to always connect all BCON data lanes from
X0 to X3.
For more information about pixel formats and bit depths, see Section 5.2.8.1 on
.
