SN65HVD251DR_UCC2895DWTR Introduction

The TI BAW oscillator is an electronic oscillator circuit that utilizes the piezoelectric effect to generate a stable electronic signal through the mechanical resonance of a vibrating miniature acoustic resonator (BAW). This precise high-frequency signal provides a clock and timing reference for electronic systems.

With the advent of 5G networks and next-generation communications technology, many sectors from business to healthcare, agriculture and education will be affected. ?? Once communications infrastructure is in place to support the transfer of large amounts of data, businesses and governments will want to provide wireless coverage for point-to-point connections over the last mile, from objects communicating with each other in warehouses to communicating smartphones, thermostats, Between heart rate monitors and many other devices.

"Quartz crystals require additional components to extend their accuracy -- over time -- as their performance changes beyond controllable temperature changes," he added. In addition, Solis said, "using a BAW resonator is more efficient than using a quartz crystal. precise.

The basic structure of the BAW filter is that two metal electrodes sandwich a piezoelectric film (the thickness of the Quartz substrate is 2um at 2GHz), and the acoustic wave oscillates in the piezoelectric film to form a standing wave.

(Global TMT July 13, 2021) Texas Instruments (TI) has launched a new line of high-performance microcontrollers (MCUs) that advance real-time control, network connectivity and intelligent analytics at the edge. With the new Sitara AM2x family of MCUs, engineers can use 10 times the computing power of previous flash-based MCUs. The high-performance AM2x family closes the growing performance gap between MCUs and processors, enabling designers to push performance limits in applications such as factory automation, robotics, automotive systems, and sustainable energy management.

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles. It can also propagate in a vacuum. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.

"Wireless networking is at the heart of this data migration, and the ability to connect the last mile through connected devices is a critical part of the data loop." said Ray Upton, vice president of TI's Interconnect Microcontrollers Group: Large amounts of data to make accurate and informed decisions is a very important innovation capability.
