This question is still regarding to AD9970.

I have genertated good CCD analog input signal to AD9970s but without digital output data.

 

I have used the same register setting for other AD9970s but with good digital output.

 

          x"08101000000", -- 20

           x"080F3ffffff",

           x"080E3ffffff", -- PBLK  toggle position

           x"080D3ffffff",

           x"080C00dc05a", -- CLPOB toggle position

           x"080B0000000", -- for test only

           x"080A0000000", -- HBLK end position

             x"08090400000", -- HBLK mask for H1,H2, H3, H4 and HL. H2and H4 high

           x"08080000000", -- HBLK length in mode 1 and mode 2

           x"08070000000",

           x"08060000000", -- 10 HBLK start position

           x"08053ffffff",

           x"08043ffffff",

           x"08030064000", -- HBLKOeven line

           x"08023ffffff",

 

 

I am afriad my HBLK and CLPOB settings are wrong.

 

My input CCD signals are progressive, 1280 pixels per line with 1220 active pixels.

 

There is 900 lines per frame with 34 inactive lines.

 

Please help me to see what is the potential problems.

 

Many thanks.

 

David.
