Hello netland !

I have the following problem in speeding up the 68901 UART:

I want to double the frequency that is fed into the MFP as
rx/tx clock. This signal is derived from a 2.4576 MHz clock
that is accessible. The frequency range is 3000 Hz to 700 kHz
and the output pulse must remain synchronous to the 2.4576
Clock.

Any hints on how to digitally double some clock will be
greatly appreciated.

Solutions using gate-runtime are not applicable because the
spectrum is too wide.

Many thanks in advance for your efforts, 
  Bjoern
