AD9923A - Triggering Exposure and Strobe

We using the AD9923a together with a progressive scan CCD. The timing ist proved and stable. We try to configure triggered still image capture with long time exposure. The Sensor needs only one Field and the still image readout timing is the same as live preview. We are able to span the exposure over multiple frames. We can generate a strobe pulse, as long as the pulse is in the very first field. But the the strobe output stays active, if the strobe pulse spans over field boarders. We studied the manual multiple times but we are not able to find the reason - any clues what to look for?

 

Setup:

- Still image uses 4 Fields, supress HD / VD (Reg 0x63 0x1004)

- Strobe uses Shut2

- Shut 2 (Reg 0x77) 0x000002 - no manual control / active high

 

Thanks in advance
