TECH NOTE: Adding Protection when Switching Inductive Loads

This technical paper will explain the importance of adding protection to the load terminals in all inductive load switching applications by reviewing important inductor behaviors.   Topics Discussed: Inductor Behavior Using Simplified Low-Side Switched Inductor or Relay Coil (Sinking) Examples RL Charging (Storage) Cycle RL Steady State (Fully Charged) Traditional RL Discharge Cycle without Protection but…

What are PMC and XMC Modular I/O Standards?

PMC and XMC Modular I/O – Established Standards in High Performance Systems The IEEE standard for PCI Mezzanine Cards (PMCs) initiated the first successful approach to truly modular I/O devices. Subsequent development has presented system integrators with the XMC modules, introducing support for switched interconnect protocols, adding contacts serial lanes for high-speed data transfer, and providing better…

TECH NOTE: Speed for A/D Converters

In this article, we will consider the basic conversion methods that are commonly implemented on commercially available boards and how these methods affect the throughput and accuracy of the data. Some Important Terms Resolution – The number of discrete values that a converter can produce over the range of analog values. A 12-bit A/D converter…

A to D Digital Converter Tech Note

Inside a Multiple Channel Analog to Digital Converter We will look at a common technique to implement A/D conversion in a Commercial Off-The-Shelf (COTS) board. The information is helpful in determining how to wire a system with multiple A/D sources. A/D Sampling Techniques Multiplexing Inputs A very cost-effective way to implement an A/D conversion board…

How do FPGA Modules Drive Real-Time Applications?

FPGA Modules with an Integrated Processor Drive Real-Time Applications Engineers developing DSP and high speed logic applications are now well-aware that FPGA modules can help them create an integrated, sophisticated solution. The availability of commercial off-the-shelf (COTS) FPGA boards can make these solutions viable and do so in reduced development times. Today, with systems architected…
