PDN Design and FPGA Transceiver Performance

PDN designs targeting transceiver (SERDES) FPGAs require clean voltage sources with strict voltage rail requirements. This document describes the advantages of modern switching voltage regulators in a power distribution network (PDN) design to achieve the best FPGA transceiver performance. This white paper provides guidance on voltage regulator selection for low-noise applications, and a test case that demonstrates the transceiver performance for different types of voltage regulators and voltage rail configurations.
