Most engineers think of flat cable as inexpensive wiring that runs between computer peripherals. But not all flat cable is created the same. There is a special category of flat cable that excels in uses where space efficiency isn’t the only consideration. What’s called Extruded Flexx-Sil™ cable is designed...
This introduction to EPAD MOSFET describes a broad selection of devices with precisely set gate threshold voltage values, including zero threshold made, enhancement mode and depletion mode. Furthermore, novel circuit designs are presented to illustrate how these devices can be used at a practical level. The brief circuit...
This application note provides an introduction to the DDR memory technology and explains common challenges, related to the specific nature of DDR data, command / address and control buses and describes the typical measurements to verify and debug DDR system designs.
The paper explains the recommended test points and...

Design and verification engineers will be learning the importance of ensuring a stable operation and of reducing the risk of failure after any change over the product’s lifetime. Both require a solid characterization of the memory interface.
We will be discussing test and tool requirements such as bandwidth,...
It is much lower cost and causes far fewer problems to use a single power converter correctly rated for the application rather than two or more in parallel. However, there are power converters which feature master slave parallel operation. These units are intended for modular expansion schemes and fault tolerant parallel...
Lattice Semiconductor has introduced two low cost FPGA families with SERDES, the LatticeECP2M, introduced in 2007, and the most recent family, the LatticeECP3. The ECP2M and ECP3 FPGAs provide designers with the best of both worlds: a high performance, low-cost FPGA fabric with built-in high performance SERDES.
These...
In recent years passive intermodulation (PIM) has become a major concern for wireless service providers and those responsible for building and maintaining wireless networks. The increase in awareness around PIM comes with the increasing complexity of how spectrum is utilized.
The push to increase spectral efficiency...
Fractional turn transformers are not a new idea but it's not a concept that appears to have been applied to AC/DC power supplies in the past. For multiple output power supplies in particular it offers some significant advantages in terms of saving space, cutting cost and improving efficiency.
The challenge...
Many moderate size Programmable Logic Device (PLD) designs, especially those in control plane applications, consist of a number of interfaces interconnected via an onchip bus to a microprocessor that may be on- or off-chip. Although each interface is often relatively simple, the task of building all the on-chip interconnections...
Your sump pump is your home’s first line of defense against flooding. Without battery backup during a power outage, your sump pump will stop working and your home will be placed at risk.
For anyone with a little mechanical aptitude, a DIY system consisting of an inverter/charger and one or more batteries...
Although not part of the PCI Express spec, nontransparent bridging is completely consistent with it and can support multiprocessor systems with only minimal software initialization efforts.
For PCI Express technology to realize its full potential as the interconnect solution for chip-to-chip and backplane switching...
Current fiber optic technology fails to deliver a High Performance Interconnect solution which provides service and manufacturability, high density channel count, low loss optical performance and high reliability.
New broadband service networks, high fiber densities, increasing end - user bandwidth demands and...
Today's high reliability military, aerospace, and industrial applications require more rugged, light - weight filter connectors. The filter connector provides a stray signal barrier upstream and away from electronic devices to protect critical circuits from electrical interference, without affecting system function...
While it’s clear that reductions in size and improvements in efficiency are constant pressures in the design of AC/DC power supplies, the medical device market has some particular requirements that make the challenge greater still. This article considers these challenges and looks at how recent AC/DC switching power...
