As modern bus interface frequencies scale higher, care must be taken in the printed circuit board (PCB) layout phase of a design to ensure a robust solution. Table of Contents

General layout guidelines for printed circuit boards (PCB), which exist in relatively obscure documents, are summarized. Some guidelines apply specifically to microcontrollers; however, the guidelines are intended to be general, and apply to virtually all modern CMOS integrated circuits.

Harness our diverse suite of tools, models and simulators to select the right integrated circuit, identify external components and values, analyze your system- or product-level design, and even export it to your favorite computer-aided design (CAD) environment.

It is often the case that a circuit’s schematic is correct, but does not work, or perhaps works with reduced performance. In this post, I will show you how to properly lay out an operational amplifier (op amp) circuit PCB to ensure functionality, performance, and robustness.

What Are PCB Parasitics? •An ideal printed circuit board has no impact on a circuit’s performance –Circuit behaves exactly as designed & simulated on the schematic level •In reality, certain PCB layout techniques, electronic components, and other materials create “extra” circuit elements •These are known as parasitics!

In particular, we have provided recommended starting points for layout when using the popular LM267x, LM259x and LM257x families (Figure 1) The focus is on the step-down (Buck) Simple Switcher ICs from Texas Instruments, but the same principles hold for any topology and switching power application.

Table 1 outlines the high-speed interface signals requiring the most attention when laying out a PCB that incorporates a Texas InstrumentsTM System-on-Chip (SoC). Table 1. Critical Signals. Not all referenced interfaces are present on all Texas Instruments SoC devices.

电机驱动系统的 PCB 设计非常重要,需要通过特殊考量并采用特殊技术才能实现出色性能。 电源效率、高速开关频率、低噪声抖动和紧凑的电路板设计,是设计人员在确定电机驱动系统的布局时必须考虑的几个主要因素。 德州仪器 (TI) 的DRV 器件非常适合此类系统,因为它们高度集成并配备完善的保护电路。 本应用报告旨在重点介绍使用 DRV 器件进行电机驱动器布局时需要注意的主要因素, 并提供相关的最佳实践指南,确保在电机驱动应用中实现一种能够降低热应力、提高效率并最 …
