TLV62569ADRLT_LBCA2HNZYZ-711 Introduction

Kim Wong, vice president and general manager of TI's High-Speed Data and Clocking Group, said: "The clocking requirements for future communications infrastructures will far exceed the device performance of current quartz crystal resonators. By integrating TI's BAW resonators directly into clocking devices , we can achieve ultra-low jitter performance and resiliency to meet the increasingly stringent requirements for data pipeline resistance to vibration and shock in the process of communication transformation.”

Among them, 42 150mm fabs and 24 200mm fabs were closed, while the number of closed 300mm fabs accounted for only 10% of the total. The details are shown in the figure below. According to IC Insights statistics, in the past 10 years (2009-2018), all 11-ball semiconductor manufacturers closed or rebuilt a total of 97 fabs. .

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.

. In order to keep the acoustic wave in the piezoelectric film to oscillate, there must be sufficient isolation between the oscillating structure and the external environment to obtain a small loss and a large Q value. On the other side of the oscillating structure, the acoustic impedance of the piezoelectric material is not much different from that of other substrates (such as Si), so the piezoelectric layer cannot be deposited directly on the Si substrate. The propagation speed of sound waves in solids is ~5000m/s, which means that the acoustic impedance of solids is about 105 times that of air, so 99.995% of the sound wave energy will be reflected back at the boundary between the solid and the air, which is the same as the original wave (incident wave). together to form a standing wave.

The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid. For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves. .

Ladder type can be used on single-ended (single-ended/unbalanced) and differential (balanced) signals, while lattice type is more suitable for differential (balanced) signals.
