Abstract

"Channel bandwidth and manufacturing process have become two limitations in today's high speed designs. In order to overcome the channel bandwidth limitation, multilevel signaling is seen as one of the ways to achieve higher data rates. Using multilevel signaling as the coding scheme will impose new challenges in high speed serial link design. Due to manufacturing limitations, only transmission lines with meshed ground planes are allowed in some applications. Meshed power and ground planes have been widely used in today's flexible PCB designs to satisfy repeatability installation and reliability requirements.

In Section 1, high speed serial link design with PAM4 signaling is investigated. Specifics of DFE and FFE equalizers for PAM4 are discussed. Tests on channels with different properties are done to reveal the advantages and drawbacks of PAM4 compared to NRZ.

In Section 2, an equivalent transmission line model is used to extract the effective characteristic impedance of the transmission lines with meshed ground planes. The results are confirmed with full-wave simulations. Then by using DoE method, the characteristic impedance can be predicted when the geometry is in a given range"--Abstract, page iii.
