NXP Unveils Ultra-Compact, High-Precision MEMS Frequency Synthesizer

15.01.2012

NXP Semiconductors unveiled an ultra-compact, high-precision MEMS clock synthesizer at CES 2012 that the manufacturer claims will be an excellent alternative to crystal clocks. Instead of a quartz resonator, it uses a silicon crystal, which makes the novelty 20 (and even more) times more compact than the smallest resonators to date.

A MEMS crystal, unlike a quartz crystal, does not require special ceramic or metal cases for sealing. It can be housed with other ICs in an inexpensive standard plastic case. The crystal-free frequency synthesizer is just one example of a range of advanced high-performance mixed digital-analog component technologies that NXP is showcasing at CES 2012.

NXP's MEMS resonator technology provides higher frequency stability, lower jitter, and much less clock temperature drift than other CMOS oscillators. The company's industrial prototype is a highly stable frequency reference that is ideal for Gigabit Ethernet, USB, PCI Express, and SATA communications equipment, as well as CPU and memory synchronization, and control circuits in consumer electronics devices.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Giant tensoresistive effect 03.01.2009

For more than half a century, the so-called tensoresistive effect has been known to physicists and is widely used: some materials change their resistance when they are deformed.

This principle is used, for example, by sensors that trigger airbags in a car: a strong blow shakes the sensor, its electrical resistance changes, and an impulse is applied to the explosion of a special powder, the gases from which instantly inflate the pillow. For materials known so far with such properties, the resistance to deformation changes by 10-100 times.

A group of physicists from Switzerland, England and France recently synthesized a material from aluminum and silicon that changes its resistance upon impact by almost 900 times. It is believed that thanks to this discovery, the size of piezoelectric sensors can be reduced to such an extent that they can be embedded in electronic microcircuits and nanotechnology.
