PP XMC/M02 dual XMC/PMC carrier board provides a flexible solution for designers wishing to add functionality to 6U CompactPCI systems by using XMC or PMC modules. The carrier can accommodate two single or one dual width, PMC or XMC modules conforming to the IEEE 1386 Common Mezzanine Card standard. The PP XMC/M02 can support up to 100 MHz PCI/PCI-X PMC modules and x4 PCI Express XMC modules. A wide range of XMC/PMC modules can be supported, including processor modules (Root-Complex or Monarch), SAS, SATA, LAN, WAN, Graphics and Communications Controllers. The PP XMC/M02 board supports the CompactPCI hot swap mode which enables live insertion and extraction of the carrier allowing modules to be added, replaced or upgraded without interruption to the system operation. Rear I/O signals from each of the XMC/PMC sites are routed via either PMC Pn4 or XMC Pn6 rear I/O connectors to the CompactPCI J3 and J5 connectors. For harsher environments an extended temperature version is supported.
