DS1087L 3V EconOscillator Single Chip Broadband Oscillator

25.11.2003

Dallas Semiconductor introduces the DS1087L, the world's first 3V broadband single-chip EconOscillator.

This instrument has a fixed operating frequency and does not require any programming. With an output smoothing ratio of 2% or 4%, the DS1087L has 20dB less spurious EMI than comparable crystal oscillators. The EconOscillator DS1087L is a clock generator that generates a broadband (smoothed) fixed frequency square wave in the range from 260 kHz to 133 MHz.

The device allows you to replace the crystal oscillator and reduce the level of peak radiation by smoothing the output signal by 2% or 4%. The DS1087L has a low power mode and an output blocking function, which makes it suitable for use in power critical applications.

The DS1087L is currently available in 3V, with a 5V version planned for the near future.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Recyclable printed circuit boards 03.05.2024

Electronics play a key role in today's world, but the accompanying rise in e-waste is putting the environment at risk. In response to this problem, researchers at the University of Washington have developed an innovative technology that could change conventional wisdom about circuit board recycling. A team led by scientists from the University of Washington has created a vitrimer printed circuit board that has the unique ability to be recycled multiple times. Using advanced environmentally friendly polymers, the researchers developed a material that can be turned into a jelly-like substance using a special solvent. This opens the way for PCBs to be reused and recycled without significant loss of quality. Vitrimer printed circuit boards (vPCBs) represent significant advances in environmental sustainability. Unlike conventional plastics, which are susceptible to degradation during repeated recycling, jelly-like vitrimer retains its ... >>

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Dark energy measurement 19.08.2023

Researchers at the Faculty of Astrophysics at the University of Cambridge have unveiled a new way to measure the mysterious dark energy, a hypothetical form of energy thought to be responsible for the accelerated expansion of the universe. Instead of studying the galaxies of the early stages of the Universe, scientists turned their attention to the movement of the Milky Way and Andromeda, two neighboring galaxies that are directly approaching each other.

These two giant galaxies are approaching each other and are on their way to a future collision. Under the influence of the gravitational forces of approach, they will slowly begin to rotate around a common center of mass, and each complete revolution will take about 20 billion years. However, long before the completion of this cycle, in about five billion years, the Milky Way and Andromeda will begin to merge.

According to research, in this process, forces acting in different directions will act on galaxies. Gravity will bring them closer, as Einstein's theory predicts, but the possible dark energy should also have a counter-force.

Scientists have developed a model based on the masses of galaxies and their orbits to establish an upper limit to the cosmological constant. This model is the simplest description of dark energy. The study showed that existing uncertainties can cause readings that are up to five times larger than those obtained using observations of distant supernovae.

It should be noted that the current degree of estimation error remains quite high. This approach was presented more as a demonstration of a method that needs further improvement. The researchers suggest that modern NASA space telescopes can significantly improve the accuracy of measurements of the masses and trajectories of galaxies, as well as reduce the level of error.

In addition, the proposed method can be applied to analyze the approach of other galaxies. Together, different measurement approaches can help confirm the existence of the mysterious dark energy and explore its nature.
