Dear,

 
 

 
My customer is designing a camera with AD9928 and On-Semi CCD 29M(KAI-29050).

 
1) The output of H1A~H4A and H1B~H4B looks OK, but there is no output at RG_A, RG_B.

 
2) When driving vertical clock, showed over current at V1T~V4T.

 
 

 
Is there any debugging points for these issues ?

 
Is thers a reference register setting table or souce for interfacing with KAI-29050 ?

 
 

 
Thanks a lot.

    We do not have any reference settings for this CCD. It's possible that On-Semi might have something for a similar CCD.
    
 
    Try checking the RG drive and RG mask register settings to make sure they are all programmed correctly. Also, any Sequence registers that are not used should always be set to 0x0 to avoid any unintended masking behavior.
    
 
    The V-clocks should be debugged with the CCD disconnected.
