Make Signal Integrity Work for You – A Practical Guide for Designers

了解为什么通道完整性会在后期失效。遵循一份包含八个步骤的规格检查清单，在早期就在重定时器、连接器、电缆、材料和测试之间分配裕量。

Release of the DDR5 standard was announced in July 2020, about 18 months after the announced development of the first RAM module following the proposed standard. The standard allows peak speeds in excess of 5200 MT/sec/pin (compare that to 3200 MT/sec/pin with DDR4), with JEDEC-rated speeds up to 6400 MT/sec/pin and channel bandwidth increased up to 300 GB/s. Demand for this new generation of memories with 8, 16, and 32 GB capacities should

Multi-board PCB assemblies must adhere to signal integrity rules and ensure low EMI. These two aspects are intertwined, as explained in this comprehensive guide.

Introduction Signal reflections and the engineering related to impedance matching are one of the basic topics related to design of high-speed digital systems. In the case of digital system with a high bit rate, in which information about the state of bits "0" and "1" is sent in the form of a square wave signal, it is assumed that the rise (or fall) time of the rising and falling edges are negligible in relation to the binary signal frequency. In

Expert Tara Dunn answers what are semi-additive PCB fabrication processes and what are the benefits? Read now and learn more about SAP.

In this series of articles, we will be looking at some of the different types of Serial Communication Protocols available to transfer information between microcontrollers, data-producing and data-processing peripherals, and other smart devices. The articles that follow this introduction to serial communications will cover some of the more popular protocols in common usage. At the end of this series, we will summarize the advantages and

In this article, we will be looking at the popular UART device. It’s not a communication protocol but rather the physical circuit used in microcontrollers or stand-alone ICs to transmit and receive serial data. It supports the series of articles we’ve produced to look at some of the different types of Serial Communication Protocols available. Serial communications are the perfect mechanism for transmitting information between devices such as

In this series of articles, we’re looking at some of the different types of Serial Communication Protocols available for transferring data between devices. The articles will cover a few of the more popular protocols and standards in use today, and at the end of this series, we will recap and compare the advantages and disadvantages of each. We hope this information will prove valuable next time you need to implement a serial communication bus in

Via impedance calculators are only useful in the low frequency range, where impedance control is typically not needed.
