I hope it is okay when I ask a technical question relating to the electronics design of the camera!
I'm actually working on a CCD-Camera with the KAF1001 from OnSemi and I'm also using the AD9826 for sampling the video data (CDS-Mode). My schematics for the AD-conversion are pretty much the same then for the ICX453AQ-chip.
I'm having issues with the AD9826: When I connect the ADC to the output buffer circuit (after the KAF1001 output stage) the pixels in the beginning of every line have a higher intensity. This is shown in the camera picture and on the scope.
But when I disconnect the AD9826 from the output buffer the effect is totally gone - the KAF1001 outputs normal pixel values.
=> see attachments.
- How do you clock the AD9826? Continuously or triggered? Do you clock the ADC only when you want to have an image (snapshot, triggered) or do you have CDSCLK1, CDSCLK2, ADCCLK running all the time?
- Did you ever had something similar when connecting your CCD with the AD9826 and if yes - how do you solve it?
Would be very great to have a response
Thanks so far!
