Functional Description
MVME8100 / MVME8110 Installation and Use (6806800P25G) 82
The PMC/XMC sites are fully compliant with the following:
 VITA 39 -PCI-X for PMC
 VITA 35-2000 for PMC P4 to VME P2 Connection (PMC/XMC1 site only)
 PCI Rev 2.2 for PCI Local Bus Specification
 PCI-X PT 2.0 for PCI-X Protocol Addendum to the PCI Local Bus Specs
 IEEE Standard P1386-2001 for Standard for Common Mezzanine Card Family
 IEEE Standard P1386.1-2001 for Standard Physical and Environmental Layer for PCI Mezzanine Card.
 VITA 42 for XMC
 VITA 42.3, PCIe for XMC
PMC/XMC sites are keyed for 3.3V PMC signaling.
MVME8100 / MVME8110 provides a x8 PCI Express interface link for PMC/XMC1 and x4 PCI Express interface
link for PMC/XMC2. It is designed such that same PCI Express interface is used for either the XMC or the PCIe
to PCI-X bridge required for a PMC. This is made possible by using Pericom PI3PCIE3412 PCIe mux devices.
The PCIe Mux at both sites is controlled by the CPLD. The CPLD detects the presence signal provided by the
XMC or PMC board and it will be used to configure the routing of PCIe Mux accordingly.
4.14.1 PMC Add-on Card
The MVME8100 / MVME8110 supports up to two PMC cards. PCI-X operation to each site is provided using
a separate IDT TSI384 PCIe to PCI-X bridge for each site. Each Tsi384 can support up to 8.5Gbps (64bits x
133 Mhz). An onboard switch will configure the TSI384 to run on either 100 MHz or 133 MHz. The default is
133 MHz.
The MVME8100 / MVME8110 supports multi-function PMCs and Processor PMC's (PrPMCs). The PCI
signaling voltage (VIO) for the site is 3.3V as required by the Tundra Tsi384 and is keyed as such. The power
budget allocated to 3.3V is 16.5W (max) for either PMC or PrPMC. The PMC site has two IDSELs, two
REQ/GNT pairs, and EREADY to support PrPMC modules as defined by VITA39.
