Camera Link video timing Figure 11.4:
Time between FVAL rising edge and first LVAL rising edge tg1 •
≥
16 Tp.
LVAL inactive period tg2 •
≥
4 Tp
Time between last LVAL falling edge and FVAL falling edge tg1 •
≥
16 Tp ,
where Tp = interface clock period
Note that the LVAL signal is not a continuous signal and that the time between successive LVAL
periods (tg2 in the timing diagram) is not fixed but depends on the image format and possibly inserted
shutter operation. For details on shutter operations during image readout please refer to chapter 7.
