AD1833CST_AD2702UD Introduction

. The history of human beings' struggle with noise can be traced back to primitive society. Covering your ears in fear of thunder is an early noise reduction method for human beings. Nowadays, many related products have been derived from traditional noise reduction methods, such as earplugs, sound insulation cotton, sound insulation panels, etc., which are passive noise reduction by surrounding the ear to form a closed space, or using sound insulation materials such as silicone earplugs to block external noise. High-frequency noise can play a good role in suppressing, but it is powerless to low-frequency noise, and it cannot fundamentally solve the noise.

It is reported that Renesas expects to close two more 150mm fabs in 2020 or 2021. In addition, Renesas has adjusted its factory in Otsu, Shiga Prefecture, Japan, to manufacture optoelectronic devices. Taking Renesas as an example, the company's two recently closed fabs are both 150mm, including a factory in Kochi Prefecture, Japan, which mainly produces analog, logic devices and some old-fashioned micro components. From a regional perspective, Japan closed a larger number of fabs.

. In the past year, ADI has been in constant action, and news of cooperation with a well-known car company has been frequently reported. We can also get a glimpse of some new trends in automotive application innovation.

. Sometimes, however, noise is not always a bad thing, and this is especially true for particularly quiet electric vehicles, for which ADI announced last year that it offers DSP-based internal and external engine sound for electric and hybrid vehicles, using the ADSP-BF706 digital signal processor and Electric Vehicle Warning Sound System (EVWSS) firmware to help automakers in North America and the rest of the world meet future safety regulations for external engine sounds at low speeds in electric and hybrid vehicles.

Taking TWS (true wireless Bluetooth headset) as an example, the active noise reduction function has also become a "just-needed" function for product market competition. "Sophie, Marketing Manager of Industrial and Medical Consumer Products of ADI's China Business Unit, said in a recent interview. "Faced with the increasingly strong demand for active noise reduction for the next generation of TWS headphones, how can upstream manufacturers provide high-performance chips and algorithm solutions to help Importing products to customers and quickly bringing them to the market is the key for TWS earphones to seize market opportunities in the 'second half' competition. .

. TI's new product announcement includes an industry-first crystalless wireless microprocessor (MCU) that integrates a TI BAW resonator in a package. Design engineers can use this MCU to achieve simpler and smaller designs while improving performance and reducing cost. Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals.

TI's new newer SimpleLink™ multi-standard MCUs with ?BAW technology can be integrated into low-power wireless RF devices, such as low-power crystalless Bluetooth and Zigbee? technology, thereby reducing wireless RF failures caused by external crystals.
