White Paper: Considerations For High Speed PCB Track Design In 10Gb/s Serial Data Transmission

By Steve Bowers and Dr. Herbert Lage, Avago Technologies

This white paper describes the main considerations in the design of a PCB for the transmission of 10 Gb/s serial data. It has been written to aid the PCB designer with the layout for a host board for use with the Avago Technologies' 10 Gb/s HFCT-711XPD XFP LC differential serial transceiver and the electrical channel to the SerDes IC (XFI channel). The focus is on the frequency-dependent attributes of the various components within the electrical channel. In addition, the parametric issues of a pluggable connector are examined.
