SPI vs. I2C For Memory Access

SPI vs. I2C: How to Choose the Best Protocol for Your Memory Chips

One of the common implementations of SPI and I2C in a PCB layout is as a protocol for reading and writing to an external Flash memory. Flash chips are a very common component in embedded systems and can offer high capacities of non-volatile memory up to Gb values. When choosing a memory chip, you'll want to match the application requirements and functionality with the bus speed you need for read and write operations in your memory chip. There is also the matter of the type of Flash memory you'll need to access (NOR vs. NAND).

Is There an SPI Trace Impedance Requirement?

There is no SPI trace impedance requirement? The reality is that SPI lines only start to need impedance control when the length of the interconnect becomes very long. And because there is no specific impedance requirement in the bus, you have some freedom in channel design and termination. So what exactly qualifies as “very long” and when is some termination method needed? We’ll break it down in this article.

What You Need for PCB Packaging and Shipping

When you get your PCBA back from an assembler, you’ll notice the packaging materials used to pack and ship the PCBA. Those materials are specific to electronics, and if you build products on behalf of clients, it’s important to know the packaging materials used for packing and shipping electronics. In this article I’ll show the main set of materials and equipment used to package electronics assemblies.

How to Make PCB Gerber Files in Altium Designer Step-by-Step

Once you've got your PCB layout finished and you're ready to start preparing for manufacturing, one of the critical steps is to create PCB Gerber files.

Should You Place Teardrops on Differential Pairs?

One of the major factors impacting reliability of a PCBA is the use of teardrops on traces in the PCB. Like many aspects of reliability, the considerations also span into the signal integrity domain, particularly as more high-reliability products require greater data handling capabilities and run at higher speeds. In this article, I’ll break down the issues present in teardrop usage on differential pairs and how these may affect impedance.

Designing to performance standards, whether the baseline IPC standards or more stringent industry standards, is the first step in ensuring a reliable circuit board. In this e-book, readers will gain a thorough look into PCB testing and analysis, starting from basic tests performed on bare boards and completed assemblies.

Where to place AC Caps on PCIe Lanes

AC Coupling Capacitors in PCIe Routing

Coupling capacitors find plenty of uses in analog applications and on differential protocols, acting essentially as high pass filters that remove DC bias carried seen on a signal. In the case of PCIe, there are a few reasons to place AC coupling capacitors on differential pairs beyond the fact that AC coupling capacitors are listed in the standard. In this article, we’ll look briefly at where to place coupling capacitors on PCIe links, as well as the reasons these are placed on PCIe links.

The Positive Impact of Supply Chain Visibility on Design to Cost

Design to cost is a lofty idea that is only perfectly executed when supply and demand for components are in perfect harmony. Unfortunately, the current landscape for component sourcing makes design to cost more of a balancing act rather than an exercise in price reduction. To help designers in their efforts to balance cost, capabilities, and procurement, we created this ebook to help users understand how modern supply chain tools can help in these complex design problems.

Evaluating Stubs on PCIe Lanes
Blog
A Brief Study of Stubs on a PCIe Connector

Stubs are an important topic in high-speed PCB design, and there is a longstanding guideline that stubs should always be removed from all vias on high-speed digital interconnects. While stubs are bad for high-speed lines, they do not always need to be removed. What is more important is to predict the loss profile and frequencies, and to floorplan appropriately to try and prevent such losses.

Surface Layer DFM and Cleanup

PCB Layout Cleanup Before Manufacturing

Once you finish your placement and routing in your PCB layout, it can be tempting to wrap up the layout and send everything in directly to manufacturing. The reality is that the board may still need some work before it is considered finished. The cleanup you perform at the final stage of PCB layout will help you catch any outstanding errors that can't be programmed into your DRC engine, and it gives you a chance to add any outstanding details to the surface layers.

How to Get 3-port S-parameters From a 2-port VNA Measurement

S-parameters are fundamental quantities in signal integrity, and an ability to understand them from measurement or analysis is very important. If you have a 3-port network, like a power divider or circulator, it may appear that you must use a 3-port VNA to measure these S-parameters. It is always acceptable to measure between two ports, but you need to know what exactly it is you are measuring. In this article, we’ll look at the relationship between the true 3-port S-parameters with a 2-port measurement.
