* I think this works as follows:
|
|
*
|
|
* subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096
|
|
*
|
|
* Presumably, when dda3 is added in, it gets to adjust the dda2_inc value
|
|
*
|
|
* So,
|
|
* dda1_ideal = subcarrier/pixel * 4096
|
|
* dda1_inc = floor (dda1_ideal)
|
|
* dda2 = dda1_ideal - dda1_inc
|
|
*
|
|
* then pick a ratio for dda2 that gives the closest approximation. If
|
|
* you can't get close enough, you can play with dda3 as well. This
|
|
* seems likely to happen when dda2 is small as the jumps would be larger
|
|
*
|
|
* To invert this,
|
|
*
|
|
* pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size)
|

*
|
