XCVR_RX_SD_THRESHOLD
Receiver Signal Detection
Voltage Threshold
Specifies signal detection voltage
threshold level. The following
encodings are defined:
■ SDLV_50MV=7
■ SDLV_45MV=6
■ SDLV_40MV=5
■ SDLV_35MV=4
■ SDLV_30MV=3
■ SDLV_25MV=2
■ SDLV_20MV=1
■ |SDLV_15MV=0
For the PCIe PIPE PHY. Changing from
the default value for any other protocol
results in a Quartus II compilation
error.
