ISI / Molex PCIe XMC x8 Lane Adapter
ISI / Molex PCIe XMC x8 Lane Adapter allows a single-width XMC module to be used in a PCI Express slot. The XMC module is compatible with VITA 42.3 and supports up to eight PCI Express lanes. This adapter is completely transparent to PCI Express. All signals from the PCI Express host bus are connected directly to the XMC module. The XMC P16 connector is routed to SATA connectors for signals at speeds up to 3GHz. The connectors provide a simple way to patch-panel communications links between cards. The XMC Jn4 connector routes differential matched-length pairs to the MDR68 connector at the back of the card. The SMA connectors provide special support for trigger and timing inputs to innovative XMC modules.
More power to the XMC module may be provided by using an optional power connector to the adapter card. The power connector delivers +12V to the adapter and powers the on-card 3.3V, 15A DC-DC power supply. Power to the XMC VPWR inputs is configurable using jumpers on the card. ISI / Molex PCIe XMC x8 Lane Adapter mounts to the adapter using standoffs and with the end-bracket. The bracket mates to standard PMC end brackets and supports an EMI gasket.
