shows the OOB signal detection options.
Enables the internal Out-of-Band signal detector (OOB). OOB signal detection is used
for PCI EXPRESS and SATA.
Specifies a binary value representing a differential receive signal voltage level. Valid
values are 110 and 111, with 111 recommended. When the signal drops below this
level it is determined to be an OOB signal. This option is not available if the Use RX
OOB signal detection option is not selected.
See the Spartan-6 FPGA GTP Transceivers User Guide for more information about the
OOB Detection Threshold levels.
