8.2.1 LPDDR4 Board Design and Layout Guidelines

The goal of the Jacinto 7 DDR Board Design and Layout Guidelines is to make the LPDDR4 system implementation straightforward for all designers. Requirements have been distilled down to a set of layout and routing rules that allow designers to successfully implement a robust design for the topologies that TI supports. TI only supports board designs using LPDDR4 memories that follow the guidelines in this document.
