LUT-Assisted Clock Data Recovery and Equalization for Burst-Mode 50-100 Gbit/s Bandwidth-Limited Flexible PON

We demonstrated LUT-assisted CDR and equalization for burst-mode $50-100 \mathrm{Gbit} / \mathrm{s}$ bandwidth-limited PON, achieving signal recovery under large 100 ppm frequency offsets and 0.5 UI phase mismatch using reduced 50 ns preambles, with 0.3 dB sensitivity penalty only.
