Hello Mike,



> I don't understand what you mean by "Also, note that you will need a
> jumper in the choice of the phase detector output (JP3, JP4, or JP5)."
> How do I decide?
> 
> Also - I see in r2_enhpps_30_1.txt that N1, N2, N4, and N8 as well as
> R0..R5 are accounted for.  What shall I do with the remaining "N" spots
> (16..2048)?
> 
> Finally, in r2_enhpps_30_1.txt it refers to "using the 00 configuration
> (ID-5000)" in the section about selecting ld_conf.  What is the 00
> configuration?

> |Hi Chris,
> |
> |You are right, save the 0-ohm resitors (jumpers) for last.  
> |The ones you will populate depend on the application you 
> |choose.  Luis has documented the jumpers in the text files 
> |that come with the configuration files on his web
> |site:
> |
> |http://gref.cfn.ist.utl.pt/cupido/reflock.html
> |
> |There are the jumpers of the N and R registers (which really 
> |generic jumpers now).  Also, note that you will need a jumper 
> |in the choice of the phase detector output (JP3, JP4, or JP5).
> |
> |Start with the the lowest profile parts first.  That will be 
> |the resitors and caps.  The parts sheet make it easy to go one 
> |value at a time.  Mark off the designator as you populate the 
> |parts.  If you need help in knowing where the part goes, take 
> |a look at the assembly file on Luis' web site.  It has a 
> |magnified view of the silkscreen.  You can double check with 
> |the schematic.
> |
> |All the parts should solder onto the board in a straight 
> |forward manner.
> |
> |I trust you have done surface mount parts before?  I use a 
> |magnifying glass for most parts.  But the CPLD I soldered down 
> |under a stereo microscope. All the remaning parts can be done 
> |under a lighted magnifying glass.
> |
> |If you have any questions, please ask on the list.  We'll jump 
> |in to help you.
