Signal Integrity Considerations 

  Traces of differential signals pairs are NOT routed symmetrically (as symmetric pairs). 

 Traces of differential signals pairs are NOT routed with equal length. For applications where traces length has to be matched or timing differences have to be compensated, The tables below list the trace length of I/O signal lines measured from FPGA balls to B2B connector pins.  

 Traces of differential signals pairs are routed with a differential impedance between the two traces of 60 ohm.  

 Pairs of pins that form a differential I/O pair appear colored together in the table. An electronic version of these pin-out tables are available for download from the Trenz Electronic support area of the web site.
