5.1.3 Camera Link timing
It might be interesting to know when “valid data” can be expected exactly.

LVAL – t
L v d
Every line has periods with no valid data. The Duration of None Valid
Data between two lines (
t
nvd
) is three time the Camera Link clock (clk).
Delay before every first line is 2 times clk.

Frames are not sent permanently. Between two frames will be a gap –
even at highest frame rates. Minimum duration between two valid frame
signals is the duration of one line.
