NB3N3020 - new frequency multiplier

29.01.2009

ON Semiconductor introduced the NB3N3020, a programmable frequency multiplier with high precision, low phase noise, and low edge jitter.

The chip provides both LVPECL and LVCMOS clocks from a single device, enabling the NB3N3020 to be used in a wide range of applications, including networking, consumer electronics, and computers. The IC has three frequency select pins with three LVCMOS logic levels, which provide a choice of one of 26 frequencies, allowing designers to meet the requirements and replace multiple clock sources in various systems with one customizable chip.

ON Semiconductor's NB3N3020 Programmable Frequency Multiplier has a wide output frequency range from 8 MHz to 210 MHz. The microcircuit uses quartz with parallel resonance at the first harmonic with a frequency of 5,0 ... 27 MHz or an unbalanced clock source LVCMOS with a frequency of 2,0 ... 210 MHz for operation and generates a differential LVPECL output and an unbalanced LVCMOS output signal of the selected frequency, which is obtained by multiplying the input frequency.

When the output enable (OE) LVCMOS signal is low, the chip disables the clock outputs, which allows developers to control the presence of clocking in systems being created.

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, ... >>

27" 5K monitor Philips Brilliance 275P4VYKEB 12.09.2015

For those to whom 4K is already not enough, Philips has decided to release a monitor with a larger resolution - 5K (5120 x 2880 pixels). The Philips Brilliance 275P4VYKEB model has a diagonal of 27 inches and is based on a PLS-matrix with a pixel density of 217,57 ppi and a color depth of 10 bits.

The monitor has a wide color space coverage (100% sRGB and 99% Adobe RGB) and supports Flicker free technology, responsible for the absence of flicker at all brightness levels. Thus, this model does not contribute to rapid eye fatigue.

Philips Brilliance 275P4VYKEBThe maximum declared brightness of the display is 300 cd/m1000, the contrast ratio is 1:178, the viewing angles are 8 degrees vertically and horizontally, and the response time is 275 ms. As for interfaces - Philips Brilliance 4P1.2VYKEB is equipped with two DisplayPort 3.0 connectors and three USB 2.0 ports, one of which is designed for fast charging of mobile devices. True, the manufacturer does not specify what technology is used for this. Perhaps we are talking about Quick Charge XNUMX.

The Philips Brilliance 275P4VYKEB has a Pivot feature that allows you to use the monitor in portrait mode. And thanks to the support of the VESA mounting standard, the device can be hung on the wall. The monitor also has built-in stereo speakers (2 watts each), a 2-megapixel webcam and a microphone.

Power consumption is about 69 watts, while in ECO mode it is about 45 watts.
