Hi all
look at Blatt 7
the signals c, d, e must not be generated!
You save one FF and can use it for the interpolator.
Use signals f and its komplement for frequency
switching (Blatt 4).
Isn't it easy like that?
I found out that it is importand for the cxl's to
get 50% 2,9MHz and 50% 4,4Mhz.
With the old comlicated timing it is 33,x% 4,4MHz
and 66,y% 2,9MHz. This causes variationes in the
DC offset of the cxl (don't know why
)
If one wants the new timing card, I'll email it.
