AD1584CRTZ-REEL7_AD22100ST Introduction

. Combining EtherCAT, Ethernet and CAN FD: In terms of galvanically isolated architecture, the new microcontrollers feature a fast serial interface with 8 receive channels, enabling chip-to-chip communication at speeds up to 200 Mbps with fewer pins.

According to TI, creating high profit margins is related to their use of 12-inch fabs to produce analog chips and reduce costs. The data shows that TI's analog chips had an operating profit margin of 46.7% in 2018, but the operating profit margin of embedded processors was only 29.6%. In the analog chip market, manufacturers like TI, ADI, and Maxim all have gross profit margins higher than the industry average. Take TI as an example, its profits and profit margins have maintained an upward trend over the past 10 years and reached new highs in 2018.

. A cohort of students is expected to enroll in ISE courses in September 2022. Through industry placements, students gain experience working in companies (which make up nearly half of the total coursework), allowing them to acquire the skills they need in a real work environment under the guidance of a mentor.

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.

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. Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. 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.

Professor Kerstin Mey, Vice-Chancellor of the University of Limerick, said: "ADI is our firm and strong long-term partner, and I am delighted that ADI is working with us on this exciting new project. We are looking forward to working with ADI to achieve this Important ways to reshape the way future software engineers are trained.”.

The reflector consists of several layers of alternating high and low impedance layers. For example, one 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 waves will The reflected back and the original wave are superimposed. 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. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer.

. 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.

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.
