How does MEMS oscillator pursue better timing accuracy?

MEMS oscillators can provide a highly stable reference frequency that can be used to manage data transmission, define radio frequencies, and sequence electronic systems. They are becoming more and more important for many applications such as avionics, field and satellite communications, precision GNSS, aerospace, etc. Major manufacturers in this field include SiTime, Jauch Quartz, Raltron Electronics, Abracon Holdings and Microchip Technology. Let us focus on the major recent developments in this field.

SiTime releases aerospace and defense MEMS timing solutions

SiTIme, a wholly-owned subsidiary of MegaChips in Japan, is a global leader in MEMS timing solutions. In July this year, SiTIme announced the launch of the new Endura series MEMS timing solutions. The Endura product portfolio covers six oscillator types and 17 products. All devices provide programmable options such as frequency, operating voltage and stability. In addition, some devices also provide dedicated programmable functions, such as spread spectrum, pull range, and differential output types. Endura products have the highest two-level acceleration sensitivity, as low as 4 ppt/g (typical value). The extensive product portfolio provides customers with a large number of choices and the ability to configure each device according to application requirements.

"When subjected to high-strength shocks, vibrations and extreme temperatures, traditional timing components are prone to failure, reducing system performance and reliability," said Piyush Sevalia, Executive Vice President of Marketing of SiTIme. "In order to solve these problems, SiTIme created silicon Based on MEMS oscillator system, analog circuit, compensation algorithm and advanced packaging, its performance is better than any other available timing solution under harsh environment. For example, Endura high precision TCXO provides 4 ppt/g acceleration sensitivity, which is better than traditional Quartz-based solutions are 50 times better. With this performance, we believe that Endura will change the aerospace and defense oscillator market."

Tekmodul launches precise timing synchronization solution

Tekmodul, a German supplier of wireless data communication radio modules, announced the launch of the Atops NTS7500 "Grandmaster Clock". It is equipped with Stratum 1 NTP (Network Time Protocol) server, which can communicate directly through Stratum-0-clock one-to-one connection. The equipment is expected to play a key role in the field of energy distribution.

"The NTS7500 Grandmaster clock is designed to ensure the efficient operation of switchgear in large-scale intelligent systems. Our world is becoming more and more intelligent, and the smart grid will become the key to meeting the growing global energy demand. Therefore, the overall energy of switchgear in the long-term The distribution field plays an important fundamental role," Tekmodul said.

Microchip supplies the industry's "smallest" MEMS clock generator

Microchip Technology is a publicly listed microcontroller, mixed-signal, analog and Flash-IP integrated circuit manufacturer in the United States. It is now offering the industry's "smallest" MEMS clock generator DSC613 series. This series can replace up to three crystal oscillators, thereby reducing the space occupied by sequential components by up to 80%. It includes two low-power fractional phase-locked loops (fractional PLL), which provide leading frequency flexibility and powerful jitter performance.

Customers can configure the output frequency, control pin function, package size, PPM accuracy and temperature range. According to the load of the customized circuit board, up to three output drive strengths can be provided. You can also use spread spectrum clock technology to reduce electromagnetic interference (EMI). Microchip acquired MEMS timing technology through the acquisition of Discera and Micrel in 2015.

Jauch Quartz and Endrich establish cooperation

Jauch Quartz, a supplier of quartz crystals, crystal oscillators, MEMS oscillators, and battery technology, recently announced a partnership with distributor Endrich. At the same time, the company also released a new MEMS JSO15 TR solution. Due to its characteristics, MEMS JSO TR is very suitable for high-precision real-time clock applications, such as mobile medical equipment and health monitors.

In addition, its low power consumption makes it useful for wearable devices, smart watches, and motion trackers to extend the battery life of these battery-powered devices. The extreme temperature stability of the MEMS JSO15 TR solution makes this MEMS oscillator very suitable for smart meters installed outside buildings. The MEMS JSO TR can be powered by a variable supply voltage of 1.5 V to 3.63 V, resulting in a frequency deviation of less than +/- 1.5 ppm.
