NPCIe-UPLINK-O

The NPCIe-Uplink-O is a PCIe interface card, which allows establishing an x16-PCIe-link between the optical uplink of the NAT-MCH-PHYS80 and a PCIe-host.

The heart of the NPCIe-Uplink-O is a Broadcom PEX8733 PCIe switch. With station 0 ports, it connects to the PCIe host via the edge card connector; station 1 ports are linked to the optical transceivers (one or two Finisar BOA FBOTD10SL1L00). It can be configured to use one x16 or two x8 optical uplink(s).

The switch owns a SSC isolation clock input, so it is not mandatory to use a common clock in the whole PCIe hierarchy, even if the host is using a SSC reference clock.

Moreover, the PEX8733 makes a dedicated driver on host side needless, as the required settings can be made via the configuration EEPROM of the switch.

The NPCIe-Uplink-O features a Lattice MachX02 FPGA as hardware extension of the on-board Atmel ATxmega128 microcontroller. Moreover, it handles PCIe side band signals coming from the edge connector and hot-plugging functionality for the attached MTCA system.
