So I am developing a high speed networking system using the Cyclone V and more specifically it's XCVR IPs. Everything appears to function apart from one peculiar thing. The rx_std_signaldetect line as I understand it tells you when you have a sender of data, however I can't seem to ever deassert it, when the line is disconnected in external loopback the flag stays high. There isn't an overabundance of information about it online either.
Can anyone explain under what conditions it is deasserted?
