Figure 4 : I2 C digital isolator vs. optocoupler

Isolated power : Another area where the use of digital isolator technology has benefited this design is with the generation of very low level isolated power supplies. Two ADuM5000 devices were used to generate isolated 5V supplies with up to 500mW of power output capability. These were used to power the analog side of the Σ-Δ converters which float with the rapidly changing motor voltage. These isolated supplies use the same technology as the data isolators so they have an internal transformer switching at 180MHz. This frequency is 3 orders of magnitude higher than standard DC-DC converters allowing for ta much smaller size. The ADUM5000 devices are a simple way to provide low power isolated voltages all in an SOIC-16 package.

Multilayer ceramic capacitors (MLCCs) are used extensively in modern electronics because they offer high volumetric efficiencies and low equivalent series resistances at attractive prices. These advantages make MLCCs nearly ideal for a wide range of applications, including output capacitors for power supplies and local decoupling capacitors for integrated circuits. The various types of MLCCs are delineated primarily by their temperature coefficient, which is the amount of variation in their capacitance over a specified temperature range. Class I types, given a designation of NP0 or C0G, must vary less than +/–30 ppm over their operating temperature range, while Class II types can change anywhere from +/–15 percent (X7R) to +22 percent /–82 percent (Z5V) [1].

The temperature coefficient of an MLCC is a direct effect of the materials used in the ceramic that forms the capacitor dielectric. Furthermore, the dielectric material also determines the electrical characteristics of the capacitor. Class II dielectric types (X7R, Z5U, Z5V), often are referred to as high-k” ceramics because their dielectric materials, have relative permittivities that range from 3000 (X7R) up to 18000 (Z5U). Class I C0G capacitors tend to have relative permittivities in the range of six to 200 [1]. The benefit of increased relative permittivity of the dielectric material is that high-k MLCCs are available in much larger capacitance values and smaller packages than C0G types.

As Microsoft does its about-face on Xbox One (wisely deciding the customer is always right), iFixit has posted its teardown of Xbox 360 E, which iFixit calls a mid-2013” end-of-360-series game console but being the first console with the XBox One design.

The brand new(ish) Xbox 360 E is designed to resemble the much-anticipated Xbox One,” writes Miroslav Djuric, chief information architect at iFixit, in a press release. As the Xbox 360 line is nearing its end, we figured that this new release probably wouldn't presage any dramatic hardware transformations. But we were curious if the Xbox's new looks would affect its repairability. So, we handed the device over to our teardown monkeys for disassembly.”

Here's an excerpt from those iFixit teardown monkeys of Microsoft's Xbox 360 E, which iFixit calls a mid 2013 revision to the Xbox 360” game consoles and possible facsimile to much-anticipated Xbox One.”

LTE is the latest generation mobile network technology, and the fastest growing standard in telecoms history. With the exponential increase of video-rich content and remote data storage, LTE has been designed to meet the growing demands of the Internet for both human-to-human, human-to- machine and machine-to-machine communications.

LTE will accelerate and enhance numerous technology trends including last-mile connections, multimedia-rich web applications, security and cloud computing. This article briefly summarizes the history of mobile data networking, and how LTE’s bandwidth and latency improvements will change the face of the web.

The fastest growing telecom standard Digital mobile communication was born in the 1990’s as an offshoot of the fixed wired telephony industry in the form of 2G GSM, which initially offered voice as the primary service. Later on, data was added as a lower priority add-on” feature, first as SMS for text messaging and then as packetized data through GPRS and then HSPA. Interestingly, SMS, the first commercially available mobile data service, today generates over 100 billion dollars in annual revenue worldwide.

Increasing memory density, system-on-chip (SoC) memory content, performance, and technology-scaling combined with reduced voltages increases the probability of multi-bit transient errors. Notably, transient errors are no longer restricted to aerospace applications. Now applications such as biomedical, automotive, networking, and high-end computing are susceptible to transient errors and have a need for high reliability and safety.
