5.0Gbps 4-Lane PCIe 2.0 ReDriver with
Equalization & Emphasis
Register Description
Byte 0 - Signal Detect (SIG)
SIG_xy=0=low input signal, SIG_xy=1=valid input signal
Bit
76543210
Name
SIG_A0
SIG_B0
SIG_A1
SIG_B1
SIG_A2
SIG_B2
SIG_A3
SIG_B3
Type

Power-on
State
XXXXXXXX
Note: R=Read only, W=Write only, R/W=Read and Write, X=Undened, rsvd=reserved for future use
The Signal Detect register provides information on the instantaneous status of the channel input from the Input Level
Threshold Detect circuit. If the input level falls below the Vth- level the relevant SIG_xy bit will be 0, indicating a low-
level noise or electrical idle input, resulting in the outputs going to the high-impedance off state or squelch mode. If the
input level is above Vth-, then SIG_xy is 1, indicating a valid input signal, and active signal recovery operation.
Byte 1 - Receiver Detect Output Register (RX50)
LB_xyxy#=0=loopback mode, LB_xyxy#=1=normal mode, DE_x=0=pre-emphasis, DE_x=1=de-emphasis
Bit

Note: R=Read only, W=Write only, R/W=Read and Write, X=Undened, rsvd=reserved for future use
The RX50_xy bits report the result of a receiver detection cycle. One bit is assigned for each channel of the device.
RX50_xy is at a logic 1 level indicating a load and receiver was detected. When RX50_xy is 0 then a load device was
not detected. The RX50 register is read-only, and is undened after power-up until a Receiver Detection cycle com-
pletes.
Byte 2 - Loopback and Emphasis Control Register (LBEC)
LB_xyxy#=0=loopback mode, LB_xyxy#=1=normal mode, DE_x=0=pre-emphasis, DE_x=1=de-emphasis
Bit
