Each electronic system must have a heartbeat-clock signal, which can help each component run perfectly.
For decades, designers have been using quartz crystals to produce such electronics. The precise rhythm is achieved by crystal oscillation. However, when these expensive crystals are worn, they will jitter or jump, which in turn affects the accuracy of the timing.
Recently, Texas Instruments (TI) have released two new core products based on BAW, BULK ACOUSTIC WAVE resonator technology. These miniature timer sizes are only 100 microns, which are small than the hair diameter, but their operating frequency is much higher than quartz crystals, achieving more excellent system performance.
With the arrival of 5G communications and big data age, the data transmission rate between the global system is increasing, and the high precision clock becomes more and more important.
From the various applications from building automation to virtual health, new products based on Ti BAW technology can fundamentally enhance the performance and application running speed of internal clocks.
In the past, BAW resonator techniques were often used to filter signals in communication technologies such as smartphones. In the industry, TI first uses this technology to integrate clock function.
No quartz: Industry first-free wireless MCU
TI This new product included in the industry included the industry's first non-crystallized wireless microprocessor (MCU), which integrates a TI BAW resonator in the package. Design engineers can take advantage of this MCU to complete simpler, smaller design, and improve performance and reduce costs. Since designers do not need to screen, calibrate and assemble external quartz crystals, it has accelerated product listing.
Ray Upton, vice president of TI Interconnect Microcontroller Division: "By using and analyzing a large amount of data, sensible decision is a very important innovation ability. Wireless network is the core of this data migration, pass The ability to connect the device to the last mile of the connection is a key part of the data cycle. "
By 2022, the Expenditure of the Internet of Things is expected to increase from $ 151 billion in 2018 to $ 1.2 trillion. This substantial growth shows that the Internet of Things applications are in-depth penetration. The 90% executive of technology companies, media and telecommunications companies said that the Internet of Things is the core of their business strategy.
Ray Upton said: "One major bottleneck for the promotion of Internet of Things applications is not high integration, and no crystallized wireless technology can bring huge advantages for Internet of Things applications."
TI's new SIMPLINK multi-standard MCU is integrated into a low-power radio frequency device, such as low-power radio frequency devices, such as low-powerless transistor Bluetooth and ZigBee technologies, thereby reducing wireless RF faults caused by external crystals.
Eliminate clock noise: Digital noise is reduced based on network synchronizer based on Ti BAW technology
Another product released by Ti is BAW technology-based network synchronizer, using quartz crystals to reduce digital noise or jitter. These noise and jitter typically come from the input signal of the communication subsystem of the wired or wireless hardware infrastructure in the data center core network. Eliminate noise will bring many advantages to telecom systems such as 5G networks.
Kim Wong, a vice president and high-speed data and clock business, said: "Clock requirements for future communication infrastructure will far exceed the performance of the current quartz crystal resonator. By integrating Ti BAW resonator directly into clock equipment We can achieve ultra-low jitter performance and elasticity, which meets the increasing demands of data pipes in the process of anti-vibration and impact in communication transformation. "
Working principle of miniature timer
The Ti BAW oscillator is an electronic oscillator circuit that uses a piezoelectric effect to generate a stable electronic signal by a mechanical resonance of a micro-acoustic resonator (BAW). This precise high frequency signal can provide clock and timing reference for the electronic system.
Products based on TI BAW technology can provide a variety of advantages for design engineers:
• Smaller size. Integrated into chip packages, circuit designers do not need to install separate clock devices on boards.
• Most of the energy consumption is lower. Many Internet of Things applications require quick opening of clock systems. The oscillator based on Ti BAW technology is 100 times faster than quartz crystals.
• Smaller digital noise. The TI network synchronizer chip provides the best to have the best equipment in the current market.
• Clean clock. TI BAW resonators provide ultra-clean timing reference, which is important for high-speed data transmission per second. It can also be integrated into a wireless radio frequency (RF) chip as a single-chip wireless solution.
Core impact
With the emergence of 5G networks and next-generation communication technology, many areas of business to health care, agriculture and education will be affected.
Once the communication infrastructure can support a large amount of data, the enterprise and the government will want to provide wireless coverage to connect to the last mile point-to-point connection, communicating from the warehouse to communication smartphone, thermostat, heart rate monitor And there are many other devices.
Ray Upton said: "By changing the design method of the system, our TI BAW resonator technology will pave the way for the next generation of industrial and communication applications."
