Advanced Mezzanine Card Base Specification

AMC.1 defines the implementation of PCI Express on AMC.0 Modules and Carriers. It is dependent upon and leverages AMC.0 for definition of the mezzanine’s mechanical, interconnect, management, power and thermal requirements. This is a subsidiary specification to AMC.0 and is limited in scope to defining Port usage and Electronic-Keying (E-Keying) parameters for PCI Express. This specification includes definition for both AdvancedMC Modules and Carriers. AMC.1 defines a single Fat Pipe Link of 1, 2, 4, and 8 Lanes. AMC.1 also defines a reference clock for use with the Fat Pipe Link. Compatibility between an AMC.1 Module and Carrier depends on a number of parameters such as their negotiated Link width and the location of the Root Complex. AMC.1 addresses only the parameters of the devices at each end of the Link which identify capabilities and requirements or can be configured to establish a compatible Module and On-Carrier device pair.

This specification, AMC.2, defines the implementation of 1 and 10 Gbps Ethernet (PICMG® 3.1 1000BASE-BX and PICMG® 3.1 10GBASE-BX4 subset of IEEE 802.3 XAUI signalling, respectively) links on AMC.0 Modules and Carriers.

The intended implementation practice will normally include at least one link of Ethernet. 1.2 Scope AMC.2 is a subsidiary specification to AMC.0 and is limited in scope to defining link usage, management and Electronic-Keying (E-Keying) parameters for Gigabit Ethernet (GbE) and 10 Gigabit Ethernet (10 GbE) on AMCs and Carrier Boards. AMC.2 may be implemented with any of the allowable sizes supported by the AMC.0 specification. Refer to AMC.0 for definition of the Module’s mechanical, interconnect, management, power and thermal requirements.

AMC.3 defines the implementation of storage devices and certain aspects of the Carrier. It is dependent upon and leverages AMC.0 for definition of the mezzanine’s mechanical, interconnect, management, power and thermal requirements. Functions are divided into Storage Server and Storage Client functions, where the former provide a data store and the latter use a data store. A more complete definition is provided in Sections 4 and 5. AMC.3 may be implemented with any of the allowable module sizes supported by the AMC.0 specification, such as single-width or double-width, full-height or half-height. Storage modules employing other fabric connections as the host interface should follow the requirements and guidelines of AMC.2, but may employ an AMC.3 Storage Client interface. For this purpose, the AMC.3 port assignments have been selected to avoid conflict with other AMC port assignments. Such modules are not “storage servers” in the AMC.3 sense, even though they provide a server function in the larger system context.

AMC.4 defines the implementation of Serial RapidIO on an AMC.0 Module and Carrier device. It is dependent upon, and leverages, AMC.0 for definition of the mezzanine’s mechanical, interconnect, management, power and thermal requirements. This specification is subsidiary to AMC.0 and is limited in scope to defining Port usage and Electronic-Keying (E-Keying) parameters for Serial RapidIO. This specification includes definition for both AMC Modules and Carrier devices. It defines usage for one or more Serial RapidIO Links. Appended to this specification is a signal integrity report prepared by the RapidIO Trade Association. It provides designers with information relevant to board and backplane design for various configurations of AMC modules in both ATCA and MicroTCA. This document is based on the AMC.0 Revision 2 specification.
