Revert back previous change to 90MHz
Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
incoming symbols and hence might run into problems at the very end of the
specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
running at 90MHz, raises lot of issues such as the need to recalculate
all of them , which is eventually very painful.
