Configuring The Receiver For Multi-Lane Applications - Xilinx Virtex-6 FPGA User Manual

Configuring the Receiver for Multi-lane Applications

To configure four GTH lanes within a Quad into a single x4 link, the GTHX4LANE port
must be tied High. When configured in a single x4 link, a change in the control settings on
the master lane also causes the same effect on the slaves, except with the POWERDOWN
ports. The POWERDOWN ports of all GTH lanes within a Quad in a x4 link should be
driven by the same source.
