There’s a lot of talk about the 3rd generation of Double Data Rate memory known as DDR3. We at Nine Dot Connects have laid out several DDR3 boards in the past three months. There is quite a bit of detail to know about DDR3 design and layout and unfortunately, there is also a lot of misinformation out there. We have waded though and analyzed the literature. We wish to share our findings and understanding with you in our latest webinar series, Double Data Rate (DDR3) Shouldn't be Double Trouble.
In our two-part series on this topic, we will first cover key concepts necessary for proper signal integrity and general DDR3 design. Topics to be covered this month are:
- Brief history of the DDR concept
- Comparison between the different generations of DDR
- The signaling and timing requirements for DDR3
- Understanding match length versus match delay
- Compensating for typical routing delay
- Using the iCD Stackup Planner to assist in delay matching calculation
In part 2, we will build upon this foundation by demonstrating the practical aspects of DDR3 layout techniques.
This latest webinar, Double Data Rate (DDR3) Shouldn't be Double Trouble, is scheduled for January 31, 2018 at 2 pm Eastern Time. For more information and to register, click HERE.

What is design with manufacturing and what does true DWM look like in operation? In this interview, I-Connect007 columnist Dana Korf explains what it will take to achieve total communication among all the stakeholders in the PCB development cycle. He also stresses the need for everyone involved in PCB design and manufacturing to stop making assumptions, even at the risk of being labeled as “that guy” who asks too many questions.

In this interview with Arjun Bangre, director of product for high-speed interface IPs for PCI Express and CXL at Rambus, the discussion revolves around new developments in CXL, PCI Express, and interoperable IP solutions that Rambus has developed.

As mentioned in the May issue of Design007 Magazine, design is performed, at times, in a vacuum. But it doesn’t have to be that way. Whenever circumstances allow, design should be performed by communicating with all stakeholders throughout the design process, hence the emphasis on the word with in DWM. Communication can occur through personal correspondence such as email and voice conversations or through more formal design meetings—in person or through videoconferencing. No matter which means of communication you prefer, it’s important to communicate early and often with stakeholders involved in the downstream processes as you bring your project to realization.
