LP5912-0.9DRVR_TLV70245DBVR Introduction

. With the maturity and progress of the process technology and the increase in market demand, more and more companies use advanced processes below 20nm to design and produce ICs and devices, which makes more and more IDMs and foundries eliminate low-efficiency production. fab.

The company currently has two 300mm fabs named RFAB and DMO56. TI outsources much of its logic and embedded IC production to foundries, but mostly produces analog chips in its own factories.

Ray Upton, TI's vice president of connected microcontrollers, explained that new technologies are critical to "moving large amounts of data in a stable manner," improving high-performance communications. .

So, does this mean that 150mm wafers are gradually withdrawing from the stage of history? The answer is no, there is still a huge market space for 150mm wafers. A large number of 150mm fabs in the industry were closed, and more and more 300mm fabs were launched and gradually achieved mass production.

The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. The reflector consists of several layers of alternating high and low impedance layers. For example, the first layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most of the wave will be reflected back and superimposed with the original wave. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer.

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.

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. .
