• Manufacturer Part Number: pi2eqx5864d
• Description: 5.0gbps 4-lane Pcie? 2.0 Redrivertm With Equalization, Emphasis, & I2c Control
• Manufacturer: Pericom Semiconductor Corporation

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
Note: R=Read only, W=Write only, R/W=Read and Write, X=Undefined, rsvd=reserved for future use
Individual control for each lane is provided for the loopback function via this register.
BYTE 3 - Channel Input Disable (INDIS)
INDIS_xy=0=enable input, INDIS_xy=1=disable input
Note: R=Read only, W=Write only, R/W=Read and Write, X=Undefined, rsvd=reserved for future use
The Channel Input Disable register, provides control over the input buffer of each channel independently. When and INDIS_xy
bit is logic 1, then the input buffer is switched off and the input termination is high impedance. This feature can be used for PCB
testing, and when only one input is used during Loopback as a demux function. When INDIS_xy is at a logic 0 state then the input
buffer is enabled (normal operating mode).
BYTE 4 - Channel Output Disable (OUTDIS)
ODIS_xy=0=enable output, ODIS_xy=1=disable output
Note: R=Read only, W=Write only, R/W=Read and Write, X=Undefined, rsvd=reserved for future use
The Channel Output Disable register, allows control over the output buffer of each channel independently. When and OUTDIS_xy
bit is logic 1, then the output buffer is switched off and the termination is high impedance. This feature can be used for PCB testing,
and when only one output is used during Loopback as a mux function. When INDIS_xy is at a logic 0 state then the input buffer is
enabled (normal operating mode).
