Zone 3 Recommendation

The Zone 3 connector in the MicroTCA.4 standard connects the Advanced-Mezzanine Card (AMC) module and the Rear-Transition Module (RTM). MicroTCA.4 defines the management on the Zone 3 connector and provides enough freedom to the designers to use an application-specific pin assignment for an AMC and RTM pair.

To improve the compatibility and modularity of AMC and RTM boards we present a classification recommendation of the Zone 3 connector pin assignment for the MicroTCA.4 standard for different classes of applications. This implies a zone description, electrical specification, electrical protection sequence, electronic keying and grounding and shielding options.
