XMC.3 SUPPORT
The XMCspan implements only the primary XMC.3 connector receptacles at locations J15 and J25. Each primary
connector uses 16 differential pairs: 8 defined as transmit, and 8 defined as receive, plus one 100 MHz differ-
ential pair for the PCI Express clock reference. A single four-lane PCI Express interface is connected between
each connector and the PEX8533 PCI Express Switch.
• PEX8533 Port 2 is connected to connector J15.
• PEX8533 Port 10 is connected to connector J25.
The XMC and XMC.3 specification use sideband signals to power, reset, identify, and manage the XMC card.
PMC AND PRPMC SUPPORT
Each of the two mezzanine card sites has a separate PCI Express-to-PCI/PCI-X Bridge, which is the Tsi384.
For PMC modules, the board supports 64-bit, 133 MHz PCI-X operation. The PCI signaling voltage for the PMC
is 3.3 V.
Each of the two mezzanine card sites implements three PMC connectors for 64-bit wide PCI/PCI-X interface
at locations Jn1, Jn2, and Jn3. Each site also implements one PMC connector for user I/O signals. Both sites
support front panel access to the PMC card, and rear panel access to PMC user I/O via connector Jn4.
PCI BUSES
The XMCspan has various PCI buses. There is one virtual PCI bus in the PEX8533 PCI Express switch, and two
physical PCI/PCI-X buses between the module sites and the Tsi384 bridge.
TSI384 PCI EXPRESS-TO-PCI/PCI-X BRIDGE
The Tsi384 is a bridge that allows the migration of legacy PCI and PCI-X bus interfaces to the new, advanced
serial PCI Express interface. This flexible device supports forward, reverse, and non-transparent bridging.
Tsi384 is equipped with a standard but flexible PCI Express port that scales to x1, x2, or x4 lanes with a maximum
of 1 GB per second of throughput per transmit and receive direction. Its PCI-X interface can operate up to 133
MHz in PCI-X mode, or up to 66 MHz in PCI mode.
On the XMCspan, the Tsi384 is a 4-lane PCI Express interface that is configured in forward transparent bridge
mode, and is connected with the PEX8533 PCI Express Switch.
PEX8533 Port 1 is connected with Tsi384 Bridge for module site 1.
PEX8533 Port 9 is connected with Tsi384 Bridge for module site 2.
