AD9807 FUNCTIONAL OVERVIEW It is possible to operate the AD9807 in one of five modes: 3-Channel Operation with CDS, 3-Channel SHA Operation, 1-Channel Operation with CDS, 1-Channel SHA Operation; and 2-Channel Bayer Mode. A description of each of the five ...
Page 13
SHA Operation This mode of the AD9807 enables single-channel, or mono- chrome sampling; it differs from the CDS monochrome sampling mode in that the CDS function is replaced with a simple sample-and-hold amplifier (SHA). CDSCLK1 becomes the sample-and-hold clock; ...

AD9807 Choosing the Input Coupling Capacitors Because of the dc offset present at the output of CCDs likely that these outputs will require some form of dc-restora- tion to be compatible with the input requirements of the AD9807. ...
Page 17
Note that a capacitor larger than 133 pF would still work, it would just take several lines to charge the input capacitor up to the full V level. Another option to lengthen T C clocking the CCD and CDSCLK1 while ...

CIS Application Unlike many other integrated circuit CCD signal processors, the AD9807 can easily be implemented in imaging systems that do not use a CCD. By disabling the input clamp and the CDS blocks, any dc coupled signal within the ...
