I have same question about ad9880 registers setting . In the attachment  file

of  thread  http://ez.analog.com/message/18364#18364

"AD9880 presets.zip" ,

 

file "5  720p-60.val" set

   <registerval addr="28" value="97"/>

   <registerval addr="29" value="47"/>

  this mean hs delay set equal 303,but for 720p60,this value shoud not be 260?

 

also in the file "7  1080p-60.val" ,set

   <registerval addr="28" value="160"/>

   <registerval addr="29" value="238"/>

  this mean hs delay set equal 238,but for 1080p60,this value shoud not be 192?

 

is it the file give wrong value  or i have misunderstand this two registers's meaning?

 

thank you!
