The above illustration shows hold time of video data, LVAL and FVAL signal to rising edge of pixel
clock.
9.7.2 Line Valid (LVAL, DVAL)
LVAL,
DVAL
Tldvh
Tldvl
LVAL and DVAL are connected internally in the camera. The timing for the LVAL / DVAL signal
shown in multiples of the pixel clock depend on the ratio of sensor/pixel clock, on selected line length,
and on video data width. Tldvh is always the same for a specific setting of the above parameters, Tldvl
my vary by one clock from line to line. The LVAL / DVAL signal is also output while FVAL is
inactive.
