LM385M3X-1.2/NOPB Power IC_LQH3NPZ100MMEL Introduction

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.

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.

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.

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

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.

. The resonator used in the Ladder type (SAW is also mentioned later) includes series and parallel. A series resonator plus a parallel resonator is called a stage, and the entire ladder type filter can be composed of several stages.

Compared with BAW-SMR, a smaller part of the membrane type is in contact with the underlying substrate, which is not easy to dissipate heat. However, the thin film structure needs to be strong enough to be unaffected by subsequent processes.
