CompactPCI®Serial Specification R3

Objectives

This specification has been developed to benefit the industry in four specific ways. These are:

1. Scalable data model interface for instrumentation and control using JSON data representation

2. Coexistence with alternate data sourcing models

3. Self-describing, composable hardware building blocks suitable for creation of automated factory equipment

4. Robust data set capable of enabling digital twinning at the machine-level

CompactPCI^® Serial defines the support of PCI Express, SATA/SAS, USB and Ethernet, concurrently. PCI Express, SATA/SAS and USB are arranged as a simple star architecture. Ethernet is a full mesh. Switch boards are not required and therefore not described. To support the high-speed serial interfaces a connector is introduced which is compatible to [IEEE1101]. The mechanical design is fully backward compatible to CompactPCI® and will interoperate with existing systems. This specification allows the implementation of hybrid backplanes: CompactPCI^® Serial with CompactPCI^® , CompactPCI^® PlusIO and/or with CompactPCI^® Express. 3U and 6U boards are supported with the main focus being on 3U. For 3U a new conductive cooling mechanical concept is introduced which allows to use all boards in a conductive cooled environment as well.

This CPCI Serial Space specification CPCI-S.1 is based on the CompactPCI Serial Specification CPCI-S.0. It describes architectural, electrical and mechanical extensions and differences to use CompactPCI Serial in space applications – but not only in space applications.
