Jacinto7 AM6x/TDA4x/DRA8x Schematic Checklist

Abstract

This application report highlights the Jacinto7 AM6x/TDA4x/DRA8x Schematic Checklist Tool, which provides board design recommendations when using selected AM6x, TDA4x, and DRA8x devices. The tool is intended to supplement the information provided in the device-specific technical reference manual and data sheet. It is not an all-encompassing list, but rather a succinct reference for board designers that highlights certain caveats and care-abouts related to different use cases. Links for additional device product pages and reference documents will be added as they become available.

The spreadsheet discussed in this document can be downloaded here.

1 Introduction

The Jacinto7 AM6x/TDA4x/DRA8x Schematic Checklist Tool provides a supplemental design check when creating designs with AM6x, TDA4x, and DRA8x devices. The tool enables customers to review critical aspects of their design as well as track which items have been reviewed and which might still need additional attention. This document provides a detailed description on how to use the spreadsheet/tool and address some of the common questions/issues that can arise.

This tool is a companion to the other processor documentation (Data Manual, Technical Reference Manual, and so forth) and does not replace it or any documentation. If there are any discrepancies between this spreadsheet/tool and other documents, the documents take precedent (unless otherwise noted).

In reviewing a schematic design, often the Checklist Tool will refer you to TI’s EVM design(s). In case of any discrepancy between TI EVMs and the device-specific data sheet, or other documentation, always follow the documentation (unless otherwise noted). Despite the designer's best efforts, the EVMs may contain errors that still function but are not completely aligned with the data sheet specification. The EVM designs are a great place for design information, but should not be considered as reference designs to be blindly reused.
