Q&A of the Month

Calculating optimal FFE/DFE settings and NRZ/PAM4 eye openings from a channel's single-bit response (SBR)

Once a channel’s SBR is available, we can quickly estimate the eye openings for NRZ and PAM4 signaling with optimal FFE/DFE equalizer settings—without lengthy simulations. Learn more
