AD1816AJS_AD261AND-0 Introduction

Systems with a communication interface often require an external application-specific integrated circuit (ASIC) or a dedicated host-controlled microprocessor, but this reduces the flexibility of the design architecture, increases complexity, and takes up space on the circuit board. . The newly introduced C2000 F2838x microcontrollers, however, do not rely on external ASICs, thereby reducing the overall solution size and the amount of material used.

Because analog ICs are the bridge between the physical world and the digital world, analog chips are widely used in end markets such as industrial, automotive, consumer and communications industries. Basically, where there is electricity, there is a demand for analog chips.

In order to gain an in-depth understanding of TI's new breakthrough in BAW technology, let's start with the principle of BAW filter: . • In the past, BAW resonator technology has been used to filter signals in communication technologies such as smartphones. For the first time in the industry, TI uses this technology for integrated clock functions.

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

The BQ25790 is available in a 2.9mm x 3.3mm, 56-pin WCSP package and is available now from TI and its authorized resellers. The BQ25792 is available in a 4mm x 4mm, 29-pin QFN package and is available now from TI and authorized resellers. Complete reels and custom reels are available on TI.com and through other channels, starting in 1,000 pieces. .

In addition to these features, the C2000 F2838x microcontrollers offer enhanced real-time control performance and greater flexibility than previous generation C2000 series microcontrollers. For more information on the F2838x family of microcontrollers, .

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.

"TI has been involved in MEMS for years. When asked why no one in the industry has built something like a BAW resonator, Upton said, "It's very difficult to develop. However, converting electrical energy into mechanical acoustics while keeping the signal stable and robust within a clean clock is not easy.

In the above-mentioned BAW-SMR and FBAR?filter diagrams, sound waves propagate in the form of longitudinal waves, that is, the direction of particle vibration and the direction of wave propagation are parallel. There are also different structures where sound waves propagate as transverse waves.

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