Chris-

2) I believe it is proposed to have some sort of programmable divider
between the 125 MHz and the QSD to divide the signal down to the desired
user frequency (7.020 MHz in your example) this may possible be realized
as a FPGA.


3) It is a quad divider so that each of the 4 phases of the 125MHz
coming out of the Johnson counter is divided down to the same frequency
that the Horton QSD needs.

At least that is how I understand it. However a diagram would be a great
aid to understanding the concept and assuring everyone is on the same
page.
