The PCI Express to XMC adapter allows a single width XMC card to be used in a PCI Express slot. The XMC site is VITA 42.3 compatible and supports a single (X1) PCI Express lane. The adapter is completely transparent to PCI Express. It helps to compensate for poor system signal quality by providing adjustable signal equalization and compensation for the high speed PCI Express signals. The P16 connector breakout provides convenient access to all P16 signals through a 78-pin D-sub connector. 20 pairs of signals from P16 are routed as differential pairs to JDP1 so that high-speed IO standards can be used in the cable. Balance 38 signals are provided as single ended. Using the optional power jack to the adapter card may provide more power to the XMC card. The power jack provides +12V to the adapter and powers an on-board 3.3V@3A and 5V@3A. The XMC card is cooled either with a fan or Conduction-Cooling as per VITA standard 20. The bracket mates to standard PMC end brackets and supports an EMI gasket. All connectors from the XMC end bracket are fully accessible. Applications include custom interfaces to XMC P16 connector & multi-card system synchronization and control. No software is required to operate the adapter.

Hardware

The adapter uses a Pericom PI2EQX4401 re-driver between the PCI Express host bus and XMC PCI Express interface. This re-driver chip buffers the PCI express lanes and clock signals. Equalization and signal amplification is programmable using the Dipswitches provided on the card. This allows the card to be tuned to operate in adverse conditions where the PCI Express signals are weak or distorted. The re-driver supports 1 active lane and is compatible with PCI Express Base Specification Rev 1.0a. The PCI Express lane operates at 2.5 Gbps. This Pericom redriver is supplied with regulated 1.8V supply.
