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.

Another product announced by TI is a network synchronizer based on BAW technology that works with a quartz crystal to reduce digital noise or jitter. Noise cancellation will bring many advantages to telecom systems such as 5G networks. These noise and jitter typically come from the input signals of the communications subsystems of the wired or wireless hardware infrastructure in the data center core network.

"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.

Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. This enables TI to introduce the industry's first crystalless wireless MCU for the embedded market, the SimpleLink CC2652RB, with the clock contained in the same chip. At just 100 microns in size, these tiny timers are smaller than the diameter of a human hair, but they operate at much higher frequencies than quartz crystals, enabling the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuitry, TI say.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

”. Ray Upton, vice president of TI’s Interconnect Microcontroller Group, said: “The ability to make accurate, informed decisions through the use and analysis of large amounts of data is a very important innovation capability. Wireless networks are 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.

The Membrane type is similar to the basic model of the BAW resonator, with air on both sides. Since the acoustic impedance of the air is much lower than that of the piezoelectric layer, most of the acoustic waves will be reflected back.
