Dear Engineer,

Whether it's CompactPCI, VMEbus, or AdvancedTCA, you have a lot of choices in power supplies.  We start with ATX supplies used by CompactPCI systems.  How do you combine VMEbus and VME64X hardware into a system?  We continue our series.

Choosing CompactPCI Power Supplies:  Review of ATX
By Kelvin Aist

In general, you may specify one of four styles of power supplies for your CompactPCI system.  Designed with specific applications in mind, each has advantages and disadvantages.  We start with ATX power supplies.  [Read On]

Are VMEbus & VME64X Really Compatible?  (Part 2 of 4)
By Kelvin Aist

In the first article, I compared differences between VMEbus and VME64X.  How do you integrate VMEbus and VME64X hardware into the same enclosure?  There are pitfalls you need to avoid.  [Read On]

What is IEEE 1101.11?

IEEE 1101.11 is a mechanical standard for rear transition modules.  CompactPCI and VME64X adopted this specification.  It defines a rear card cage, per IEEE 1101.10, and dimensions for rear transition modules.  These modules are 3U or 6U in height by 80 mm deep.  (Six depths are permitted, but 80 mm is most common.)
