For reliable and efficient system verification and debug of DDR3/DDR4 memory designs, comprehensive compliance test and analysis tools are required. While measurement capability and usability are critical to speed up the verification and debug process, it is equally important to choose the right probing solution and use...

MIPI D-PHY is a practical PHY for typical camera and display applications. It is designed to replace traditional parallel bus based on LVCMOS or LVDS. However, many processors and displays/cameras still use an RGB, CMOS, or MIPI Display Pixel Interface (DPI) as interface. A bridge is often required to connect a processor...
Weatherproofing options for coaxial connections at cell sites have changed and expanded along with the cell sites themselves. Today’s more complex cell site designs demand a new type of weatherproofing solution to protect vulnerable connection points at the antenna and the remote radio unit (RRU).

Utilizing embedded microcontrollers for industrial applications requires special attention given the harsh and noisy environment. Going from a supply voltage as low as +1.5V or +3.3V to the +24V industrial world requires careful design decisions and dedicated solutions to achieve safe and reliable operation.
The following...
This paper reviews the state of the art of electric drives technology in three specific areas (a) technical requirements of high−performance ac machines control, (b) most popular electrical machines and (c) control techniques. Key development trends including the dominance of ac adjustable speed drives in new applications,...
System designers are faced with continual pressure to meet their development schedules, and need to implement designs with minimal effort and risk while maintaining maximum flexibility. By using a programmable-based approach instead of several discrete devices or Application Specific Standard Products (ASSPs), designers...
With the recent rise of the Internet of Things (IoT), 14 billion devices are now connected. However, the growth of this is also significant, by 2020 it is predicted that over 50 billion devices will be connected. With these devices connected, systems are opened up for remote access and control. In turn, this has shown...
Bringing the world's most efficient EV to market.
From cutting-edge software to minimalist materials, Aptera Motors had a goal of delivering the world's first solar electric vehicle (sEV) that was less expensive to own and more efficient than anything else on the road.
Founders Chris Anthony and Steve...

This white paper focuses on isolated digital interfaces conforming to RS-485, which continues to be the industry’s workhorse standard for data transmission. The paper provides an overview of RS-485’s common-mode voltage range (CMVR) definition, and explains how isolating a transceiver’s signal and...
The realities of finite petroleum resources and growing global energy needs along with the confidence that we are indeed experiencing global warming caused by burning fossil fuels have awakened governments and the media to “green” concerns. Both organizations and individuals have started to pay attention to...
In this white paper eGaN FET technology is applied in a high frequency resonant converter. Previously, the advantages provided by eGaN FETs in hard switching isolated and non-isolated applications were addressed.
This paper will demonstrate the ability of the eGaN FET to improve efficiency and output power density...
When first introduced, logic product offerings consisted of quad, hex and octal standard logic gates, inverters and buffers. As integration and miniaturization occurred, the demand for logic solutions continued to grow, but shifted toward “control” or “glue” logic.
Control logic...
