[time-nuts] ICS525 synthesizer performance

[Brooke Clarke]

Hi John:

I can see that  your product is very different from mine and would like 
to link to your web page if that's OK.  Thanks for posting the phase 
noise plots.

I've started a web page for my Battery Top Signal Generator ICS525, see:
http://www.pacificsites.com/~brooke/BTSG.shtml
I'm still in the process of Pushing the Limits in terms of the 
frequencies you can get out of the 525-02 but so far I've seen outputs 
between 360 kHz and 525 Mhz.

Have Fun,

Brooke Clarke
