PCI109

The PCI109 is a PCIe Gen3 x8 XMC Carrier with active cooling. The module has on-board health management CPU that scans the XMC I2C bus to discover temperature sensors, then uses the temperature sensors to actively control the fan speed. If the XMC modules does not have any temperature sensors the user can set the fan speed manually via an easy-to-use menu accessible via RS-232.

The active cooling allows the XMC module to dissipate up to 70W.

The PCIe Gen3 lanes pass thru two connectors (the PCIe edge and the XMC) which impact the signal integrity of the signal.  To compensate for any loss of signal the PCI109 has a PCIe Gen3 x8 re-timer. This will provide excellent signal integrity to the host as well as to the XMC module, allowing the module to run at full PCIe Gen3 rather than training down to PCIe Gen1/Gen2.

Further, the module provides easy access to the XMC JTAG signals as well as the on-board health management CPU RS-232 via I/O connector to the face-plate.
