[time-nuts] Thunderbolt disciplining process

The tbolt uses the DS1620S chip in the SOIC-8 package.   The DIP package has quite a bit of thermal mass and would probably not work as well.   The chip revision is the last two characters of the date code line (second line on the SOIC chips).  I am looking for a rev D chip.

------------------

What package?  I may have a '1620 sample in my junk box from back 
when they were still Dallas Semi.
