Quartz crystal oscillators are high-precision and high-stability oscillators. They are widely used in electromechanical equipment that provides stable clock signals in audio, security monitoring, and other electronic applications, as well as frequency generators and data generators in communication systems. The processing equipment generates a clock signal and provides a reference signal for a specific system. The demand for quartz crystal oscillators is growing, and the operating frequency of quartz crystals ranges from tens of kilohertz to hundreds of megahertz. Known crystal oscillators are superior to ceramic resonators because they have higher stability, higher quality, lower cost, and more compact size. They can be found in a wide range of products in the fields of military and aerospace, research and measurement, industry, automotive and consumer goods. Key players include Epson Corporation, Nippon Denpa Corporation (NDK), Osquark (ADVA), Murata Manufacturing Co., Ltd., Great Vacuum Corporation (KDS), Rakon Ltd., River Eletec Corp.

However, although quartz crystals are inexpensive to produce and continue to find many applications in clock circuits, quartz crystals are increasingly being influenced by more advanced devices such as clocks and oscillators based on microelectromechanical systems (MEMS) resonators. challenge. In fact, some estimates indicate that MEMS provide reliability 10 times better than comparable quartz oscillators.

KDS launches new oscillator

In October, Japanese KDS crystal device and resonator manufacturer and seller KDS launched its new DS1008J series differential output crystal oscillator (DOCO) in Munich. The company claims that these devices are produced as a solution to the rapidly growing data flow through mobile networks and big data in recent years, and are the "smallest and thinnest DOCO" in the world. The sizes of most differential output crystal oscillators on the market are 7050 and 5032. The 1008 size of KDS is much smaller than conventional products currently on the market. "Other latest developments of KDS include DS1008JN KDS low-voltage clock crystal oscillator (1.2V). Applications include mobile communications and short-range wireless modules; wearable devices and automotive multimedia devices.

Nihon Dempa developed a highly reliable crystal oscillator

In August, the Japanese company NDK Co., Ltd, one of the world's largest quartz crystal companies, announced the development of a new NT2016SJA crystal oscillator for mobile communications. It claims that the device can withstand severe vibrations and shocks, and as an electronic device for space use installed on satellites and rockets, it has a high degree of resistance to radiation in the space environment. The crystal oscillator has ultra-low phase noise characteristics, supports low power supply voltage, is ultra-compact and lightweight.

ADVA launches GNSS receiver for 5G

In November, the Swiss company Oscilloquartz (ADVA) launched OSA 5440, which is described as “the ultimate tool for fixed, mobile and cable network operators who want to make the most of their frequency synchronization infrastructure while preparing for 5G. The value.” The new solution provides unparalleled flexibility and scale, achieving precision, phase and time synchronization. It provides complete hardware redundancy, up to 10Gbit/s line rate and unprecedented fan-out options. "What we provide to the market is a new way to high-precision UTC traceable network timing without major investment. Our new multi-band GNSS receiver is an important milestone for network synchronization. For the first time, operators can take advantage of multi-band GNSS capabilities. The solution. This new technology has unparalleled interference and spoofing detection capabilities, coupled with our centralized AI-driven GNSS assurance suite.” said Gil Biran, general manager of Oscilloquartz.

Jauch announces the launch of a series of quartz crystals for wireless applications

Jauch Quartz GmbH, a professional supplier of German quartz crystals and crystal oscillators, recently announced the launch of the JXSxx-WA quartz crystal series dedicated to wireless applications. These crystals are provided in standard packages 2016, 2520 and 3225 and 14 special frequencies to support such as Bluetooth Low Energy (BLE), Bluetooth Smart, Zigbee, ISM, LoRa, LPWAN or any other standards used in wireless applications. standard. The company said: "Due to their high frequency stability and extremely low ESR, these special crystals meet the high requirements necessary for the Internet of Things and other wireless applications." The new version includes JO32 and JO22 oscillators. JO32 has a variable power supply voltage (1.8 V~3.3 V), very low current consumption, and adopts a ceramic/metal package with sealed joints. JO22 has an output compatible with LVCMOS/HCMOS and has a variable power supply voltage similar to JO32.

Appearance

According to a recent study, the quartz crystal oscillator market is expected to grow at a compound annual growth rate of 5.5% by 2024. Driving factors include high demand for quartz crystal oscillators in the telecommunications, consumer electronics, and healthcare sectors. Telecommunication systems such as SONET SDH require highly stable system clocks to prevent time lapse or data loss. Healthcare equipment requires crystal oscillators in products such as pacemakers, and this and other innovative technologies are expected to drive demand for crystal oscillators in this market. In the field of consumer electronics, the penetration rate of smart phones and tablet computers will become another important driving force for the crystal oscillator market.
