<DIV><FONT color=#0000ff size=2 face=Arial><SPAN class=902360723-17082009>Quick
and dirty, but it's a really nice experience to tune to DCF77 at 77.5 KHz long

Europe)</SPAN></FONT><FONT color=#0000ff size=2 face=Arial><SPAN

<DIV>Hi all,</DIV>
<DIV>I also picked up a Thunderbolt and wonder if it is a good idea to
connect it to a PLL or just build a level shifter to drive the Atlas?
The same PLL board could be used as an interface but only populate the
parts required to make the clock connection. Frank
