Figure 3 Interface connector pin assignments

 

  All pins are in a single row, with a 1.27 mm(.050”) pitch. 
  The comments on the mating sequence in Table in the section 7.3 apply to the case of back-plane 

blind-mate connector only. In this case, the mating sequences are:(1)the ground pins P4 and P12;(2) 
the pre-charge power pins and the other ground pins; and (3) the signal pins and the rest of the 
power pins. 

  There are three power pins for each voltage. One pin from each voltage is used for pre-charge in the 

backplane blind-mate situation. 

  If a device uses 3.3V, then all V33 pins must be terminated. Otherwise, it is optional to terminate any 

of the V33 pins 

  If a device uses 5.0V, then all V5 pins must be terminated. Otherwise, it is optional to terminate any 

of the V5 pins 

  If a device uses 12.0V, then all V12 pins must be terminated. Otherwise, it is optional to terminate 

any of the V12 pins.
