SWDEQ (Signal integrity optimization) 

The equalization function of transmitting channels can optimize the driver current for different cable lengths and 
materials. The table shown below lists the combinations of de-emphasized driver current (ITX –IEQ) to non-de-
emphasized driver current (ITX) for different values of “DEQ[3:0]”. 

 

Table 5: 

Status of the signals “DEQ[3:0]” related to the needed deemphasis

 

Recommended De-emphasis settings for different PCIe-X1 Cable lengths at the Upstream Port: 

2m: -1.51 

dB 

7m: -3.88 

dB

De-emphasis for different PCIe X1 Cable lengths  
at the upstream port 

2 

Bit1(L = OFF, H= ON) - DEQ1 

DEQ[3:0] 
0100 = -1.51dB 
1001 = -3.88dB 

3 

Bit2(L = OFF, H = ON) - DEQ2 

 

4 

Bit3(H = OFF, L = ON) - DEQ3 

 

Table 6: 

Setup of Dip Switch SWDEQ. Default setup is marked green. 

Note:

   The De-emphasis is calculated for the case that two CPCI Rear boards are cascaded (Upstream- and 

Downstream-Port linked) through a PCIe X1 Cable. The De-emphasis can be optimized for adapter 
boards with higher or lower insertion loss differences.
